Quick Summary (TL;DR): For Plex or Jellyfin plus Home Assistant on one small server, our best-value starting point is a modern Intel N150 mini PCAliExpress price with 16GB RAM and SSD storage, provided you mostly Direct Play and only need occasional supported hardware transcoding. The Beelink EQ14 is a sensible preconfigured option, while the ASUS NUC 14 Essential N150 suits buyers who prefer a documented barebones platform. Both have a 16GB manufacturer-stated memory ceiling; do not buy either expecting to expand to 32GB later. For more containers, simultaneous video conversion, databases or extra VMs, choose an ASUS NUC 14 Pro with Core Ultra 5 and 32GB RAM. A refurbished Lenovo ThinkCentre M720q Tiny can offer good value when the exact CPU, RAM, SSD, condition and warranty are verified. The MINISFORUM MS-01 makes sense for a serious 2.5/10GbE lab, not simply to watch films. Keep large media libraries on a separate NAS or suitable storage system, expose the GPU properly to the media server, and treat Home Assistant as an availability-critical service. This is a manufacturer-specification and software-documentation comparison, not a hands-on benchmark; the number of simultaneous transcodes cannot be promised from a processor name alone.
Best Small Home Servers for Three Workloads: At a Glance
| System / configuration | Why consider it | Verified hardware facts | Most important compromise |
|---|---|---|---|
| Beelink EQ14 N150 | Best compact preconfigured starting point | N150, 4 cores/4 threads; single DDR4 SO-DIMM to 16GB; two M.2 2280 slots; dual 1GbE or optional dual 2.5GbE depending on SKU | 16GB maximum and only four CPU threads; check exact LAN version |
| ASUS NUC 14 Essential N150 kit | Best documented N150 barebones option | N150 option; one DDR5 SO-DIMM to 16GB; 2.5GbE; 2280 NVMe plus 2242 SATA M.2 support on UK kit | RAM and storage not included; 16GB maximum |
| ASUS NUC 14 Pro, Core Ultra 5 | Best upgrade path for heavier mixed workloads | Core Ultra 5 variants; two DDR5 SO-DIMMs, up to 96GB per ASUS family page; 2.5GbE; two M.2 slots | Costs more; confirm CPU SKU, iGPU, memory and storage kit |
| Refurbished Lenovo ThinkCentre M720q Tiny | Best reuse/refurbishment candidate | 8th/9th-gen Intel Core configurations; integrated UHD graphics varies by CPU; Gigabit Ethernet on cited Lenovo SKU | Old platform; variable SSD, fan, PSU, warranty and codec support |
| MINISFORUM MS-01 Core i5-12600H | Best network-heavy home-lab option | Official store lists i5-12600H; 2×10Gb SFP+, 2×2.5Gb RJ45 and 2×USB4 for MS-01 family | Overkill for basic media/HA; check full build cost and cooling |
The shortlist is deliberately about one compute box running all three services. It is not a ranking of NAS enclosures with built-in Plex support. If your priority is drive bays and all-in-one file storage, use our separate NAS for Plex and Jellyfin hardware transcoding guide.
All hardware specifications below refer to manufacturer product pages available in October 2026. Manufacturers change regional stock and configurations; the CPU and board model alone do not guarantee that the advertised RAM, SSD, Ethernet or power adapter is included.
The Real Question: Will the Media Server Direct Play or Transcode?
Home Assistant normally uses modest CPU resources. Plex and Jellyfin can also be lightweight when a client can play the original video, audio, container and subtitle format. That mode is Direct Play. A server may instead Direct Stream by repackaging compatible streams into another container; that is also relatively inexpensive. Video transcoding is the expensive operation: the server must decode and encode video, sometimes resize it or convert HDR to SDR.
This difference matters more than a synthetic CPU score. One household with three modern televisions using Direct Play may put less load on a small N150 than another household streaming a single 4K HDR file to an incompatible remote device with subtitle burn-in. A high-bitrate 4K remux can also stress Wi-Fi or a remote internet connection even when the CPU is almost idle.
| Playback situation | Server work | What to prioritise |
|---|---|---|
| 4K film Direct Plays on a local TV | Read file and deliver data | Reliable storage/network; even entry-level compute may suffice |
| Container remux without video conversion | Direct Stream; small CPU cost | Client compatibility and network reliability |
| 1080p video conversion | Hardware decode/encode if supported | Working Intel Quick Sync or another supported acceleration path |
| 4K HDR converted to SDR | Codec support plus tone mapping; variable load | Validated GPU acceleration, drivers and realistic testing |
| Image subtitles burned into video | May force full video transcoding | Subtitle/client settings and acceleration support |
| Remote streaming over slow upload | Often bitrate reduction/transcoding | Measured upload bandwidth and client quality settings |
Plex documents the distinction between Direct Play, Direct Stream and Transcode, including subtitle burn-in. Before paying for a faster PC, inspect the Plex Dashboard or Jellyfin playback information during your own representative media sessions. There is no honest universal claim such as “N150 handles five 4K transcodes”: codec profile, bit depth, HDR tone mapping, subtitle processing, drivers and output resolution all change the result.
Plex Pass, Jellyfin and Intel Quick Sync: Check the Whole Software Path
Intel Quick Sync Video is the strongest practical reason to favour a modern Intel mini PC for this combination. The N150 has Intel Graphics and Quick Sync according to Intel. A more powerful CPU is useful for software encoding, background indexing and other VMs, but buying extra CPU cores does not automatically make a poorly configured transcoding pipeline work.
Plex: Plex says hardware-accelerated streaming normally requires an active Plex Pass subscription as well as a supported CPU/GPU, server version and operating-system setup. Check the current subscription terms before budgeting; do not assume the free Plex server will use Quick Sync. Plex notes specific exceptions for some appliances, but those are not the general mini-PC rule.
Jellyfin: Jellyfin documents Intel QSV and Linux VA-API among its supported acceleration methods. It does not require a paid Plex-style hardware-acceleration subscription. It does require the appropriate drivers, permissions and device mapping. Jellyfin uses its own FFmpeg build, so follow its current acceleration documentation rather than copying a generic FFmpeg command from an old blog.
The transcoder needs access to the physical GPU. On a Linux host or a compatible container deployment, that typically means exposing the appropriate DRM render device under /dev/dri and granting the process the necessary permissions. In a Proxmox VM, GPU passthrough or another carefully supported arrangement is needed; do not assume that installing Proxmox makes the GPU visible inside a guest. An unprivileged LXC has its own device/permissions issues. Verify hardware activity during an actual transcode before declaring success.
| Feature | Plex | Jellyfin |
|---|---|---|
| Free media-server software | Yes, with feature limits | Yes |
| Normal hardware transcoding on mini PC | Plex Pass generally required | No paid licence required |
| Intel acceleration | Quick Sync on supported hardware | Quick Sync or VA-API on supported platforms |
| How to confirm | Playback dashboard indicates hardware transcoding (often “hw”) | Playback/transcode logs and GPU activity |
| Common failure | Missing subscription, codec limitation, driver or GPU mapping | Incorrect device access, permissions, driver or FFmpeg setup |
A useful buying test is to pick two difficult files you actually own: one representative HEVC 4K HDR title and one 1080p title with your normal subtitles. Check whether your clients Direct Play them; if not, test both servers with hardware acceleration enabled and record CPU usage, GPU activity, errors and whether Home Assistant remains responsive. Those results are more relevant than someone else’s unrepeatable “streams per box” claim.
Beelink EQ14 N150: Best Practical Preconfigured Starting Point
Beelink’s current EQ14 N150 specifications describe a four-core, four-thread N150, one DDR4 SO-DIMM supporting up to 16GB, two M.2 2280 PCIe 3.0 storage positions and active cooling. It is sold with preinstalled memory and SSD configurations in some regions. The product pages show both dual-Gigabit and dual-2.5GbE versions, so check the exact orderable SKU rather than trusting a reseller title that merely says “EQ14”.
For one Home Assistant OS VM, Plex or Jellyfin and a few light services, this is a balanced machine. Its integrated graphics give the media server a supported acceleration route when the operating system and codec cooperate. The two internal M.2 positions can help separate a boot/application SSD from a media metadata or scratch SSD, but they do not make this a multi-bay NAS.
- Good fit: household Direct Play, occasional hardware transcode, Home Assistant, MQTT, DNS filtering and a few small containers.
- Important ceiling: Beelink specifies 16GB RAM maximum; do not buy for a planned 32GB/64GB Proxmox lab.
- Check before ordering: UK/EU power lead, exact Ethernet option, installed SSD type, BIOS power-recovery setting and return policy.
- Storage approach: keep bulk media on an existing NAS or an independently protected storage target; the two M.2 slots are not a substitute for a large, backed-up media library.
If you already own a capable NAS, a small N150 compute box often makes more sense than replacing the NAS just to get a faster transcoder. The NAS continues to serve files over SMB/NFS while the EQ14 runs the applications. The main new dependency is network availability between them.
ASUS NUC 14 Essential N150: Best Documented Barebones Option
The UK ASUS NUC 14 Essential kit page lists an N150 variant with one DDR5 SO-DIMM, maximum 16GB, a 2.5GbE port and support for an M.2 2280 NVMe drive plus an M.2 2242 SATA drive. The UK barebones kit is shipped without memory or storage. Its manufacturer documentation also lists supported Windows and Linux distributions; that is not a guarantee that every third-party hypervisor or GPU passthrough arrangement is officially supported.
This is a good purchase if you value a predictable parts list and want to choose the SSD yourself. A barebones quote, however, must be compared against the complete cost of an EQ14 with RAM and SSD already fitted. A barebones box that appears cheaper may end up costing more after memory, storage and any Windows licence are added.
The N150 itself has a 6W processor base power rating, but this is not the mini PC’s wall-plug idle draw. Fans, memory, SSDs, power-supply losses, Ethernet, attached USB devices and workload all contribute. Measure the assembled system with a plug-in power meter if 24/7 electricity is a deciding factor.
ASUS NUC 14 Pro Core Ultra 5: Best Headroom for Multiple Services
For a household that will add several databases, more demanding media processing, Immich, a local voice pipeline, development VMs or extra containers, the NUC 14 Pro family provides a more sensible expansion path. ASUS lists Core Ultra 5 configurations, dual DDR5 SO-DIMMs with up to 96GB across the family, 2.5GbE, M.2 storage and Thunderbolt 4 connectivity. The tall kit can accommodate an additional 2.5-inch SATA drive; check the specific chassis and SKU.
The sensible configuration for this article is 32GB RAM and a good-quality NVMe SSD, not the maximum possible processor. The extra memory makes it easier to keep a Home Assistant OS VM isolated while running a media container and additional applications. The CPU gives more headroom for library scans, subtitle operations that cannot be accelerated, background maintenance and simultaneous users.
Do not assume all Core Ultra 5 variants have identical GPU branding, media-engine capability or Proxmox support. ASUS explicitly warns that features vary by SKU. Confirm the exact model identifier and Linux graphics-driver support before paying extra for advanced codecs or a particular passthrough plan. The NPU/“AI PC” marketing is not a reason on its own to buy this machine for Plex or Home Assistant.
This is the default upgrade recommendation when an N150 would be limited by its 16GB memory ceiling. It is not a universal winner for someone whose entire media library Direct Plays and whose Home Assistant instance is already stable.
Refurbished Lenovo ThinkCentre M720q Tiny: Good Value, but Check the Actual Unit
A used business Tiny PC can be an excellent small home server when its purchase price, condition and upgrade costs are favourable. Lenovo’s PSREF shows M720 Tiny configurations with 8th/9th-generation Intel Core processors, integrated graphics and Gigabit Ethernet. The precise CPU and iGPU vary: a machine advertised simply as “M720q” is not a complete specification.
An 8th/9th-gen Core i5 configuration can provide more general CPU threads than an N150, and its memory/SSD options may suit a modest Proxmox host. But it is an older media platform. Newer video formats, especially AV1 hardware decoding, should not be assumed. Older integrated GPUs may handle common H.264 and HEVC tasks yet be a poor fit for specific modern codecs or HDR pipelines. Verify the Intel processor’s official media features and the media server’s requirements before buying.
- Request a photo of the BIOS/system-information screen with the exact CPU and installed RAM.
- Check both SO-DIMM slots, included storage, SSD health, fan noise and whether the original power adapter is supplied.
- Confirm the Ethernet controller and any optional rear port; a Gigabit model does not become 2.5GbE because a listing says “business PC”.
- Ask for the refurbisher’s warranty and return period in writing; distinguish manufacturer warranty from seller warranty.
- Budget for a replacement SSD and a clean OS installation. Treat a preloaded Windows image from an unknown seller as untrusted.
If the refurbisher charges almost as much as a new N150 unit after SSD/RAM replacement, the newer platform, warranty and media-engine features are usually more attractive. The used Tiny is a price-and-condition decision, not an automatic bargain.
MINISFORUM MS-01: Buy It for a Home Lab, Not for One Television
MINISFORUM currently lists an MS-01 Core i5-12600H barebones option, and its official family page specifies two 10Gb SFP+ ports, two 2.5Gb RJ45 ports and two USB4 ports. Those interfaces are genuinely useful if the same machine hosts several VMs, connects to fast shared storage, routes traffic between lab networks or handles multiple high-throughput services.
For ordinary Plex/Jellyfin plus Home Assistant, however, its network hardware is mostly unused. A single 4K film does not require 10GbE. The MS-01 also brings a more complicated shopping basket: memory, SSDs, suitable SFP+ DACs or transceivers, perhaps a 10GbE switch, and a UPS sized for the completed system. If you do not already have the network to exploit it, you can spend a great deal without improving actual viewing.
Choose the MS-01 if the lab architecture justifies it: multiple isolated networks, several VMs, a fast NAS, PCIe expansion plans and sufficient cooling. For one HAOS VM and one media server, a NUC 14 Pro is easier to justify and an N150 is often enough.
How Much RAM, SSD and CPU Should You Actually Allocate?
Home Assistant’s official virtual-machine instructions specify a minimum of 2GB RAM and 2 virtual CPUs. That is an installation baseline, not a guarantee that a large recorder database, voice pipeline or several Home Assistant apps will remain comfortable at that allocation. Plex/Jellyfin memory use is often modest, but library scans, metadata, subtitle processing and background containers all need headroom.
| Host RAM | Example practical layout | Recommendation |
|---|---|---|
| 8GB | 2–4GB HAOS + media server + small host overhead | Only for minimal stacks; little room for future services |
| 16GB | 4GB HAOS + 2–4GB media/OS + remaining host cache/services | Best entry target for N150; watch actual memory pressure |
| 32GB | 4–8GB HAOS + 4–8GB media/app stack + room for other VMs | Preferred when buying Core Ultra/Core i5 for growth |
| 64GB+ | Several VMs, photo indexing, databases, development services | Home-lab territory, not needed for three basic services |
The numbers are planning allocations, not measured consumption or universal minimums. Do not sum every guest’s configured maximum and assume that is its normal draw; equally, do not rely on memory overcommit to save an undersized host when simultaneous activity matters. Leave headroom for the hypervisor, filesystem cache and unexpected updates.
For storage, put the hypervisor and application metadata on a reliable SSD. A 500GB or 1TB SSD is a practical starting purchase for many small deployments, but actual requirements depend on your Plex/Jellyfin thumbnail database, transcode scratch space, Home Assistant history retention and VM images. Avoid writing large transcoding scratch workloads to a small low-end boot SSD without checking endurance and free space.
| Storage component | Practical choice | Why it matters |
|---|---|---|
| Host OS / Proxmox boot | Replaceable SSD with good health and backup plan | Recoverable platform; avoid mystery second-hand SSD |
| HAOS VM disk | Separate virtual disk with backup schedule | Simplifies snapshot/restore and capacity tracking |
| Plex/Jellyfin config | SSD-backed persistent directory | Database and artwork performance; back up separately |
| Transcode temporary directory | Fast storage with monitored free space | Avoid full root filesystem and unexpected playback failures |
| Media library | NAS share or appropriate local bulk storage | Capacity, protection and growth beyond mini-PC drive slots |
| Backup target | Independent NAS/USB/cloud destination | A VM snapshot on the same SSD is not disaster recovery |

One Host, Three Services: The Deployment Layout We Recommend
For a mixed-use x86 mini PC, a practical layout is Proxmox VE on the hardware, Home Assistant OS in its own VM, and Plex or Jellyfin in a separate Linux VM or carefully managed container. This separates Home Assistant’s OS and app lifecycle from media-server maintenance. It also gives you a place to run MQTT, DNS, monitoring or other small services without altering HAOS.
Mini PC (wired Ethernet)
└── Proxmox VE host (SSD)
├── VM 101: Home Assistant OS (official qcow2 image)
│ └── Zigbee/Thread radio via USB passthrough or network coordinator
└── VM 102: Linux + Plex or Jellyfin
├── GPU acceleration: validate supported passthrough / device mapping
├── Config and metadata: local SSD
└── Media: read-only or least-privilege SMB/NFS share from NAS
Independent NAS / backup target
├── Media library (SMB/NFS)
└── Scheduled VM/config backups + off-site copyThis is an architecture sketch, not a claim that GPU passthrough works automatically on every chipset. If media acceleration is the priority and you are uncomfortable with virtualisation, a conventional Linux host with Docker for the media server and Home Assistant Container can be simpler. The trade-off is that Home Assistant Container does not provide the full HAOS Supervisor/Apps experience; external supporting services become your responsibility.
If Home Assistant is critical to heating, alarms or accessibility, decide whether you want it sharing a host that may reboot during media experiments. A dedicated Home Assistant appliance can be a better reliability decision even if it uses a little more total electricity. For the deployment differences, read Home Assistant OS vs Docker vs Proxmox.
Networking and Radio Placement Matter More Than Another CPU Tier
Use wired Ethernet for the server. For typical household media, Gigabit Ethernet can carry several ordinary streams; the precise number depends on source bitrate and competing traffic. 2.5GbE becomes useful when the server also moves large backups, photo libraries or files to a capable NAS. A 10GbE port is only valuable when the switch, NAS, cabling and clients can use it.
Do not confuse a 2.5GbE port on the mini PC with end-to-end 2.5GbE. A Gigabit switch port in the middle caps that link. Likewise, a remote stream may be limited by your broadband upload rather than the local network. Measure the path before buying new switches.
Zigbee and Thread radios are another common trap. A coordinator attached directly to a mini PC can suffer 2.4GHz interference from nearby USB 3.x cables, SSD enclosures and metal chassis. Use a short, good-quality USB extension lead and position the radio away from the computer. If Home Assistant runs in Proxmox, map the device into the HAOS VM using a stable host-port or vendor/product approach, and test recovery after reboot. A network coordinator can avoid host-specific USB mapping but adds its own network and firmware dependencies.
Our Home Assistant on Proxmox Zigbee and Thread passthrough guide covers that implementation in detail; there is no reason to repeat it in a hardware shortlist.
How to Compare Complete Five-Year Ownership Costs
A mini PC price is not a complete home-server price. For this use case, separate the compute box from media storage and protection. If you already own a NAS, record its cost as existing infrastructure for an incremental decision, but include its ongoing electricity and replacement exposure when comparing complete architectures. Do not quietly compare a barebones PC against a fully populated NAS.
| Cost line | What to include | Common omission |
|---|---|---|
| Compute mini PC | Barebones or preconfigured unit, correct regional VAT/shipping | RAM/SSD missing from a “cheap” barebones listing |
| Memory and SSD | Compatible SO-DIMMs, boot/app SSD, optional spare | Replacement of low-quality bundled SSD |
| Bulk storage | NAS enclosure or DAS, disks, usable capacity after redundancy | Treating raw HDD capacity as usable protected capacity |
| Backup | USB rotation, second NAS or cloud, encryption media | Assuming RAID is a backup |
| Network | Switch, NICs, cables, DAC/transceivers where needed | 10GbE switch and SFP+ accessories |
| Power protection | UPS, battery replacement allowance | UPS battery ageing and shutdown signalling |
| Software | Plex Pass if hardware transcoding is required; any paid licences | Assuming every media feature is free |
| Energy | Measured wall draw for mini PC + NAS + switch + UPS losses | Using CPU TDP as wall power |
| Maintenance | Replacement fans/SSDs and your administration time | Treating old refurbished hardware as risk-free |
Electricity formula: five-year electricity cost = average combined wall power in watts ÷ 1,000 × 8,760 hours/year × 5 × your electricity price per kWh. Measure the whole installation at the socket; HDD spin-up and video transcoding make consumption vary through the day.
Five-year electricity cost (£) = (watts / 1000) × 8,760 × 5 × £/kWh
Example only (not a product measurement or a live tariff):
Mini PC 12W + NAS 24W + switch 6W = 42W average
42 / 1000 × 8,760 × 5 = 1,839.6 kWh over five years
At an assumed £0.25/kWh: 1,839.6 × £0.25 = £459.90
If a different system averages 62W rather than 42W:
20 / 1000 × 8,760 × 5 × £0.25 = £219 extra over five yearsThese are worked mathematical assumptions, not claimed Beelink, ASUS or MINISFORUM power measurements and not a statement of current UK tariff. At another tariff, recalculate. The 20W average difference is what matters: it adds 876kWh over five years, so even a higher-performance machine may be economical if it avoids other hardware, but not if its extra capability sits unused.
Worked Purchase Basket: Compare the Same Complete System
Use actual supplier quotations in this worksheet rather than relying on an arbitrary online “from” price. The following £ values are hypothetical arithmetic inputs to demonstrate the method, not verified retail prices or buying recommendations. They are intentionally held constant for shared items so the difference between two compute choices is visible.
| Illustrative input, not market quote | N150 preconfigured route | Core Ultra barebones route |
|---|---|---|
| Mini PC with CPU | £260 (example quote) | £480 (example quote) |
| Additional RAM and boot SSD | £0 (already included) | £160 (example quote) |
| Two-bay NAS enclosure | £280 | £280 |
| Two media HDDs | £340 | £340 |
| Independent external backup HDD | £170 | £170 |
| UPS and shutdown connection | £140 | £140 |
| Switch, cables, radio extension | £75 | £75 |
| Illustrative initial total | £1,265 | £1,630 |
The table deliberately uses identical NAS, disks, backup, UPS and network assumptions. The difference is £365 initial cost in this illustrative basket, before electricity, subscriptions, warranty or maintenance. Substitute real VAT-inclusive quotes, and if you already have a NAS or UPS, do not buy it twice. If you only need Direct Play, the Core Ultra premium is difficult to justify. If it prevents a later replacement because you need 32GB RAM and more VMs, it may be worth paying.
To finish the five-year comparison, add each route’s measured combined energy bill, any Plex Pass payments actually required, a realistic UPS battery allowance and any backup storage/cloud costs. For example, if both routes shared the illustrative 42W average above, their five-year totals would be £1,724.90 and £2,089.90 respectively before software, maintenance and battery replacement. Those are scenario totals, not vendor ownership-cost claims.
What to Check Before Buying: A Compatibility Checklist
- List actual clients and media: identify codecs, 4K/HDR content, subtitle types, concurrent viewers and remote streaming needs.
- Choose the media software: Plex Pass budget if you need Plex hardware acceleration; Jellyfin if its feature set and device support suit you.
- Verify exact CPU and GPU: check the manufacturer SKU and Intel graphics capabilities, not merely the mini PC family name.
- Check RAM ceiling: N150 models here top out at 16GB according to their manufacturers; a future 32GB VM plan requires a different platform.
- Confirm physical storage: identify M.2 length, NVMe versus SATA compatibility, included SSD and whether a tall chassis is required.
- Check Linux/hypervisor support: firmware settings, network driver, iGPU visibility, device mapping and ability to reboot headless.
- Plan media storage and backup: decide where large files, Plex/Jellyfin databases and HAOS backups will live.
- Check radio and USB layout: leave space for a Zigbee/Thread extension and ensure radios survive reboot and VM restoration.
- Measure power after deployment: capture idle, normal playback, active transcode and NAS disk activity at the wall.
- Test a restore: recover HAOS and media-server configuration to a separate disk or test VM before calling the system protected.
Common Problems After Consolidating Everything on One Box
| Symptom | Likely cause | First diagnostic step |
|---|---|---|
| Plex transcode pegs CPU | Plex Pass not active, codec not supported, GPU unavailable | Check Plex Dashboard “hw”, driver and GPU device mapping |
| Jellyfin falls back to software | Wrong render device, permission or FFmpeg configuration | Inspect Jellyfin transcode log and /dev/dri on relevant host |
| Home Assistant becomes slow during scans | Host RAM pressure, SSD I/O or CPU contention | Review VM memory, disk latency and host load during scan |
| Zigbee devices disappear after reboot | USB passthrough mapping changed | Check Proxmox USB mapping and device identity |
| Media library vanishes after NAS reboot | Network mount/start order and credentials | Check mount availability and service dependency before restart |
| Playback buffers although CPU is low | Wi-Fi, NAS disk access or remote upload bottleneck | Test local file read and wired network throughput separately |
| Mini PC does not restart after power failure | BIOS power-loss recovery not enabled or UPS configuration | Test controlled power recovery and clean shutdown |
| SSD fills unexpectedly | Metadata, logs or transcode scratch | Inspect directory usage and configure retention/scratch path |
Consolidation also creates a single point of failure. One mini-PC SSD failure can take down your home automations and media access simultaneously, even if the NAS still holds the films. Keep Home Assistant backups outside the host, document IP addresses and radio mappings, and retain a recovery path that does not require the broken machine to be running.
Frequently Asked Questions
Is an Intel N150 enough for Plex, Jellyfin and Home Assistant?
Often yes for a small household, especially with Direct Play and occasional supported hardware transcoding. The limiting factors are the 16GB memory ceiling, four CPU threads, the particular video conversion and how many additional services you run. Test the difficult files you actually use; do not rely on promised stream counts.
Should I run both Plex and Jellyfin at the same time?
You can run both against the same read-only media library, but each maintains its own database, artwork, metadata and potentially background scans. If you do not need both interfaces, one server is simpler. If you run both, schedule scans sensibly and monitor SSD space and CPU use.
Is Proxmox necessary?
No. It is a good choice when you want Home Assistant OS as a VM and separate media services, but it adds management and GPU/USB mapping complexity. A single Linux host with containers may be simpler if you are comfortable operating Home Assistant Container without the HAOS Apps experience.
Do I need 2.5GbE or 10GbE for 4K films?
Usually not for one normal stream. Bitrate and network quality matter more than the 4K label. 2.5GbE helps when the server also transfers large files or backups; 10GbE is primarily for a broader fast-NAS/home-lab network, not a mandatory Plex upgrade.
Should I buy a powerful NAS instead of a separate mini PC?
A powerful NAS can simplify cabling and administration, but a separate compute box allows the storage appliance to stay stable while you experiment with Plex, Jellyfin or VMs. If you mainly want disk bays, snapshots and file sharing, compare NAS models in the dedicated NAS guide rather than treating a mini PC as a disk enclosure.
Can the media library be on a USB drive?
Yes for a simple setup, provided the enclosure and filesystem are suitable, the drive is mounted reliably and you maintain independent backups. A USB disk permanently attached to the server is not an offline backup. If you expect several disks, redundancy and long-term expansion, a proper NAS or DAS may be a better architecture.
What is the most important reliability upgrade?
An independent, tested backup of Home Assistant and media-server configuration, followed by reliable SSD storage and a UPS with working shutdown behaviour. Buying more CPU cores does not protect against SSD failure, accidental deletion or a bad update.
Our Verdict: What We Would Buy for Each Household
| Household / use case | Recommended route | Why |
|---|---|---|
| Mostly Direct Play, a few smart-home services | Beelink EQ14 N150, 16GB | Preconfigured compact box with adequate baseline and Quick Sync route |
| Prefer documented barebones components | ASUS NUC 14 Essential N150, 16GB | Choose RAM/SSD; clear UK hardware specification |
| Several VMs, larger databases, future expansion | ASUS NUC 14 Pro Core Ultra 5, 32GB | Much better memory headroom and CPU flexibility |
| Low-cost refurbished option available locally | Lenovo M720q Tiny with verified CPU and warranty | Value depends on actual refurbishment quality and total cost |
| 10GbE NAS and serious multi-network home lab | MINISFORUM MS-01 i5-12600H | High-speed ports and expansion justify the complexity |
Best overall for the stated combined workload: start with a 16GB N150 mini PCAliExpress price if your library mainly Direct Plays and your service list is short. Move to a 32GB Core Ultra 5 system if you have real VM growth or heavier concurrent work. Do not pay for 10GbE or a high-end CPU to solve a codec, client, subtitle or GPU-configuration problem. The best purchase is the complete, recoverable system that matches your workload, not the smallest box with the biggest benchmark.
