Best Mini PC for NAS & Home Server 2026:
4 Picks for TrueNAS, Unraid & Proxmox
A $229 mini PC running 24/7 as your TrueNAS server, Plex host, and Docker stack costs roughly $13 a year in electricity. It’s compact, silent, and capable of replacing a tower server for most home use cases. Here are the 4 best mini PCs for the job — ranked honestly by networking, storage options, power draw, and compute headroom.
Best budget NAS/server ($229): GMKtec NUC Box G3 Plus — N150, dual 2.5G LAN, USB4, ~10W idle, Wi-Fi 6. Handles TrueNAS, Unraid, Pi-hole, Home Assistant and Docker comfortably. Best homelab compute ($489): BOSGAME M4 — Ryzen 7 8745HS 8-core, dual 2.5G LAN, OCuLink, excellent Proxmox host. Best all-rounder ($940): Peladn HO5 — 12-core Ryzen AI 9, dual 2.5G LAN, OCuLink, Wi-Fi 7 — handles Proxmox + Plex + multiple VMs simultaneously.
Why Use a Mini PC for a NAS or Home Server?
A mini PC home server gives you more compute power, more software flexibility, and often lower cost than a dedicated NAS appliance — at the expense of internal HDD bays. For most home users in 2026, this is an excellent tradeoff.
Dedicated NAS appliances from Synology and QNAP are excellent products, but they come with constraints: proprietary OSes, limited CPU options, and high prices per feature. A mini PC running TrueNAS SCALE, Unraid, or Proxmox gives you a full x86 computer — any Linux software runs natively, Docker containers work without workarounds, and the hardware can be repurposed if your needs change.
The tradeoff is storage connectivity. Most standard mini PCs lack internal SATA ports — you’ll use M.2 NVMe drives or external USB drives rather than 3.5″ HDDs. For a purely all-flash setup (NVMe SSDs) this is not a problem. For a large HDD-based media library, the Beelink ME Pro (not in our affiliate catalog but worth knowing about) is a purpose-built hybrid with 2 internal SATA bays and triple M.2 slots.
Choose a dedicated NAS (Synology) if: your primary use is storage only, you want the simplest possible setup and don’t want to configure Linux, or you need hot-swap 3.5″ HDD bays. A Synology DS423+ with 4 bays takes 20 minutes to set up; a TrueNAS build takes hours.
What to Look For — Key Specs for a Server Mini PC
For a home server mini PC, these five specs matter most: dual LAN, RAM capacity and upgradeability, M.2 slot count, idle power draw, and CPU core count for containerized workloads.
1. Dual LAN — the most important networking feature
A single Ethernet port is the bare minimum. Dual LAN is valuable in several scenarios: routing between two networks (pfSense/OPNsense), dedicated NAS traffic separated from internet traffic, or link aggregation for increased throughput to a NAS. In 2026, dual 2.5G LAN has become accessible even in budget mini PCs — it’s worth prioritizing over single-port models for any serious server build.
2. RAM — capacity and upgradeability
For ZFS (TrueNAS), the community rule of thumb is 1GB RAM per TB of storage. A 16TB NAS should ideally have 16GB RAM minimum. For Proxmox running multiple VMs, 32GB is comfortable — 16GB is tight. Critically: check whether RAM is soldered LPDDR (cannot upgrade) or SO-DIMM DDR5 (user-upgradable). Most budget mini PCs use soldered LPDDR — fine for a fixed NAS, problematic if you need to expand RAM later.
3. M.2 slots
Your operating system and Docker volumes should live on a dedicated NVMe drive. A second M.2 slot gives you fast data storage or a ZFS mirror. Budget mini PCs typically have 2 M.2 slots — enough for most setups. For all-flash NAS builds, purpose-built units like the Beelink ME Mini offer up to 6 M.2 slots.
4. Power draw — it adds up over years
A server runs 24/7. Every extra watt costs money. An N150 mini PC at ~10W idle costs ~$13/year. A Ryzen 9 machine at ~25W costs ~$33/year. A full tower at ~65W costs ~$85/year. Over 5 years, a 10W idle machine saves $180–360 versus a tower server on electricity alone.
5. CPU cores for containerized workloads
For a pure NAS (TrueNAS with just file serving), 4 cores are enough. For Proxmox running 3+ VMs or a Docker stack with Plex + Home Assistant + Nextcloud + Pi-hole simultaneously, 8–12 real cores give meaningful headroom without contention.
Which Software? TrueNAS, Unraid, Proxmox
The right OS depends on whether your priority is storage integrity (TrueNAS), storage flexibility (Unraid), or compute virtualization (Proxmox). All three run on any mini PC in this list.

#1 — GMKtec NUC Box G3 Plus: Best Budget NAS Server
GMKtec NUC Box G3 Plus — Intel N150 · Dual 2.5G LAN · USB4 40Gbps · ~10W
The most feature-complete budget home server mini PC in 2026. Dual 2.5G LAN and USB4 40Gbps on an N150 platform at $229 is genuinely unusual — this is the machine most home server builders should start with.
| Workload | Capability | Notes |
|---|---|---|
| TrueNAS SCALE / Unraid | Excellent | N150 + 16GB handles file serving & Docker |
| Plex (1080p transcode) | ✓ Quick Sync HW | 3–4 simultaneous 1080p streams |
| Plex (4K HDR tone map) | Limited | Intel UHD handles basic HDR; not ideal |
| pfSense / OPNsense router | Excellent | Dual 2.5G LAN = perfect for soft router |
| Docker (Pi-hole, HA, etc.) | Excellent | 16GB headroom for 8–12 containers |
| Proxmox (multiple VMs) | Light use | 4 cores limits heavy VM workloads |
| External NVMe via USB4 | 40 Gbps | High-speed external NAS expansion |
The GMKtec NUC Box G3 Plus earns its #1 position by delivering a combination of specs that makes no compromises for the home server use case: dual 2.5G LAN (critical for serious networking), USB4 at 40 Gbps (for fast external storage expansion), Intel N150 with Quick Sync hardware transcoding, and an idle power draw of ~10W — all at $229. The DDR5 SO-DIMM RAM is also user-upgradable, which matters for growing homelab setups.
✓ Pros
- Dual 2.5G LAN — best networking at this price
- USB4 40Gbps — fast external storage expansion
- Quick Sync — hardware Plex transcoding included
- ~10W idle — cheapest to run 24/7
- DDR5 SO-DIMM — user upgradable RAM
- Wi-Fi 6 — wireless fallback
✕ Cons
- N150 = 4 cores — limited for heavy Proxmox VM use
- No internal SATA — HDDs need external enclosures
- GMKtec smaller brand vs Beelink
- No AV1 hardware decode for Plex
#2 — Beelink EQ14 (2.5G version): Most Affordable Dual LAN
Beelink EQ14 (2.5G variant) — Intel N150 · Dual 2.5G LAN · Built-in PSU · ~$200
Beelink’s NAS-capable budget pick. The 2.5G SKU (distinct from the standard Gigabit version) adds dual 2.5G LAN at the lowest price point in this list. Built-in PSU eliminates the external power brick.
The Beelink EQ14 2.5G version offers the same core NAS capabilities as the GMKtec G3 Plus at a slightly lower price. The key differences: no USB4 (the G3 Plus wins here for external NVMe enclosures), but Beelink’s brand reputation and support community are stronger. The built-in PSU is a practical advantage — it reduces cable clutter and makes the unit more portable for lab or travel use. DDR4 instead of DDR5 is a real tradeoff: slightly lower memory bandwidth, though for NAS and light Docker workloads this is rarely perceptible.
✓ Pros
- Lowest price in the list with dual 2.5G LAN
- Beelink — strongest brand support & community
- Built-in PSU — no external power brick
- Quick Sync hardware Plex transcoding
- Wake-on-LAN + Auto Power On support
✕ Cons
- No USB4 — slower external storage expansion
- DDR4 (not DDR5) — lower bandwidth than G3 Plus
- Verify 2.5G SKU carefully — 1G variant also exists
- Single SO-DIMM channel — RAM not dual-channel
#3 — BOSGAME M4: Best Proxmox Homelab Host
BOSGAME M4 — Ryzen 7 8745HS · 8-core · Dual 2.5G LAN · OCuLink · ~$489
The step up for serious homelabbers. 8 cores and 32GB DDR5 handle Proxmox with multiple VMs, Plex 4K transcoding with AMD VCN, and a full Docker stack simultaneously — things the N150 picks can’t do.
The BOSGAME M4 transforms a home server from a single-purpose appliance into a genuine homelab platform. Eight Zen 4 cores handle Proxmox VE with 3–5 simultaneous LXC containers or VMs without contention. The AMD VCN engine enables hardware 4K HDR tone mapping in Plex — a capability the N150 machines lack. Dual 2.5G LAN means dedicated NAS traffic and internet on separate interfaces. The OCuLink port is the homelab bonus: if you ever need to passthrough a discrete GPU for a gaming VM or AI inference workload, the hardware path is available.
RAM is user-upgradable via two SO-DIMM DDR5 slots — you can go from 32GB to 64GB for more demanding ZFS pools or heavier Proxmox workloads. See our BOSGAME M4 full review for detailed benchmarks.
✓ Pros
- 8 cores — handles Proxmox + Plex + Docker simultaneously
- AMD VCN — 4K HDR Plex transcoding + AV1 decode
- Dual 2.5G LAN + OCuLink + USB4
- 32GB DDR5 SO-DIMM — upgradable to 64GB
- Wi-Fi 6E — latest-gen wireless
✕ Cons
- ~20W idle — more expensive to run 24/7 than N150
- BOSGAME smaller brand than Beelink
- No internal SATA — HDDs need external enclosures
#4 — Peladn HO5: Best All-Round Homelab Machine
Peladn HO5 — Ryzen AI 9 HX 370 · 12-core · Dual 2.5G · OCuLink · Wi-Fi 7 · ~$940
The Peladn HO5 is what you buy when you need the homelab to do everything at once: Proxmox with 5+ VMs, Plex 4K HDR, NAS storage duties, Docker stack, and optionally local AI inference — all simultaneously, without contention.
Twelve Zen 5 cores and a 50 TOPS NPU place the Peladn HO5 in a different league for homelab use. Running Proxmox with a TrueNAS VM, a Home Assistant VM, multiple Docker LXC containers, and Plex simultaneously leaves the machine with meaningful CPU headroom to spare — something both the N150 and Ryzen 7 machines can’t match under full load.
For users interested in local AI inference alongside their home server duties, the Radeon 890M and unified memory architecture run 7B–13B parameter models at interactive speeds while the home server stack continues running in the background. See our Peladn HO5 full review and our local AI guide for benchmarks.
The one limitation versus the BOSGAME M4: the HO5 uses soldered LPDDR5X — the 32GB configuration is fixed. For users who need 64GB for very large ZFS pools or heavy VM workloads, the ACEMAGIC Retro X5 (same HX 370 chip, SO-DIMM upgradable to 128GB) is the alternative to consider.
✓ Pros
- 12 cores — handles everything simultaneously
- Radeon 890M + VCN — best iGPU for Plex 4K HDR
- Dual 2.5G LAN + OCuLink + USB4 + Wi-Fi 7
- 50 TOPS NPU — local AI alongside homelab
- Windows 11 Pro included
✕ Cons
- Soldered LPDDR5X — 32GB ceiling, no upgrade
- ~20W idle — same electricity cost as BOSGAME M4
- $940 — significant investment for a home server
