# Best Mini PC for Home Server in 2026: Beelink vs Minisforum vs Intel NUC vs GMKtec
Running a home server out of a tower that draws 150W at idle gets old fast. Mini PCs have become a genuinely sensible alternative — low idle power, quiet under light load, and small enough to tuck behind a monitor or onto a shelf. The question is which one actually holds up when you’re running Proxmox with four or five VMs, a couple of LXC containers, and maybe a NAS mount or two in the background.
This comparison is aimed specifically at homelab use: Proxmox, TrueNAS, Home Assistant, self-hosted services. Not gaming, not office work. The priorities here are different from a typical mini PC roundup.

What to Look For in a Mini PC Home Server
Idle power draw matters more than peak performance. A machine that idles at 8W instead of 18W saves you roughly $20–30 CAD per year at average Canadian electricity rates — not enormous, but it adds up, and it’s heat you’re not generating.
RAM ceiling is critical for virtualization. Running Proxmox with multiple VMs on 16GB is possible but you’ll be swapping constantly. 32GB should be your floor; 64GB is better.
NVMe slots — at minimum two. One for your hypervisor OS, one for VM storage. Three is genuinely useful.
2.5GbE is now table stakes. If a mini PC ships with only gigabit in 2026, that’s a mark against it.
Dual NICs are worth paying for if you plan to use pfSense/OPNsense as a VM, or if you want to separate management traffic from VM traffic without buying a USB NIC (which introduces its own headaches).
Linux and IOMMU/VT-d compatibility — some of these machines have partial or broken IOMMU groupings that prevent proper PCIe passthrough. This is a real gotcha that reviewers often skip.

Beelink EQ12 (Intel N100)
Approximate CAD price: $220–$260 (barebones or with 16GB/500GB)
The N100 is a 6W TDP chip from Intel’s Alder Lake-N line. It has four efficiency cores, no performance cores, and tops out at 3.4GHz. That sounds underwhelming, and for heavy compute it is — but for a low-power always-on server running lightweight containers, it’s surprisingly capable.
Idle power on the Beelink EQ12 sits around 5–7W at the wall depending on RAM and storage installed. That’s genuinely impressive. Under full CPU load you’re looking at 18–22W, which is still modest.
The EQ12 supports up to 16GB DDR5 SO-DIMM — that’s the hard ceiling, and it’s a significant problem for Proxmox use. You can run a handful of lightweight LXC containers on 16GB just fine. You cannot comfortably run multiple full VMs. This is the machine’s biggest limitation.
You get one M.2 2280 NVMe slot and one M.2 2242 SATA slot. Not ideal. The 2.5GbE port is present (Realtek RTL8125), and there’s also a second 1GbE port, giving you dual NICs out of the box — a genuine plus for network segmentation.
Linux compatibility is solid. Ubuntu, Debian, and Proxmox VE install without drama. The integrated Intel UHD Graphics supports hardware transcoding via QuickSync if you’re running Jellyfin or Plex in a container.
IOMMU: IOMMU groups work, but the N100’s architecture means PCIe passthrough is limited. Don’t buy this expecting to pass through the NIC to a VM cleanly.
Best for: Home Assistant, lightweight Docker/LXC workloads, pfSense or OPNsense as a primary router (it has the dual NIC), or as a low-power secondary node.
Not for: Proxmox with multiple heavy VMs, anything that needs more than 16GB RAM.

Beelink SER7 (AMD Ryzen 7 7840HS)
Approximate CAD price: $580–$650 (16GB/500GB config)
This is where Beelink gets serious. The Ryzen 7 7840HS is an 8-core, 16-thread Zen 4 chip with a 45W TDP, though in the SER7’s chassis it’s typically power-limited closer to 28–35W under sustained load. It also includes AMD’s RDNA 3 integrated graphics (Radeon 780M), which means excellent hardware video decode support — H.264, H.265, AV1, the works.
Idle power is higher than the N100 machines: expect 10–15W at the wall in a typical Proxmox idle state. Under full CPU load you’ll see 45–60W. That’s still far better than a desktop, but you’ll notice it on your electricity bill compared to the EQ12.
RAM support goes up to 96GB DDR5 via two SO-DIMM slots. In practice, 64GB is the sweet spot — two 32GB sticks are widely available and bring the total system cost to around $750–$800 CAD all-in. This is where the SER7 earns its price for Proxmox users.
Storage is two M.2 2280 NVMe slots. That’s the minimum you want for a hypervisor. No third slot, which is a minor annoyance if you want dedicated storage for a TrueNAS VM.
The SER7 has a single 2.5GbE port (Intel I225-V or similar — check the specific revision, as early I225-V chips had errata). No second NIC. If you need dual NICs you’re adding a USB adapter or a USB-C to Ethernet dongle, both of which are workable but not clean.
Proxmox VE installs cleanly. IOMMU works properly with AMD’s virtualization stack — you can passthrough the 2.5GbE NIC to a VM if needed, and IOMMU groupings are reasonable rather than everything shoved into one group.
Drawback worth flagging: The SER7’s fan is audible under load — not loud, but not silent either. In a quiet home office at night you’ll hear it spin up. The chassis also runs warm to the touch under sustained workloads. Thermal throttling hasn’t been an issue in extended testing, but airflow around the unit matters.
Best for: Full Proxmox homelab with multiple VMs, TrueNAS in a VM, self-hosted services at scale, anything that benefits from strong single-threaded performance.
Not for: Dead-silent operation, ultra-low power budgets, or anyone who needs dual NICs without additional hardware.

Minisforum UM773 Lite (AMD Ryzen 7 7745HX)
Approximate CAD price: $520–$600 (barebones or 16GB/512GB)
The UM773 Lite uses the Ryzen 7 7745HX — an 8-core Zen 4 chip aimed at laptops, with a 55W TDP. It’s competitive with the SER7’s 7840HS in multi-threaded workloads, slightly behind in single-threaded tasks, and notably lacks the RDNA 3 iGPU. The 7745HX uses Radeon 610M graphics instead, which handles basic display output but doesn’t touch the 780M for video transcoding.
Idle power is roughly 12–18W at the wall. Slightly higher than the SER7 in our testing, likely due to the platform and Minisforum’s power management defaults. Under load it can pull 70W+ before the power limit kicks in.
RAM ceiling is 64GB DDR5 across two SO-DIMM slots. Fine for most homelabs.
Here’s where the UM773 Lite distinguishes itself for server use: it has two M.2 2280 NVMe slots and one M.2 2242 slot, giving you three storage slots total. That extra slot is genuinely useful — hypervisor OS on one, VM storage on another, backup or bulk storage on the third.
It ships with two 2.5GbE ports (both Realtek RTL8125BG). Dual 2.5GbE on a mini PC at this price is uncommon and valuable for homelab networking. You can run a dedicated management interface and a separate VM traffic interface without any adapters.
Linux support is generally good, though Minisforum’s BIOS has historically been less polished than Beelink’s or Intel’s. Early firmware on some UM773 units had IOMMU grouping issues that have since been patched. Make sure you update the BIOS before building anything critical on top of it.
Drawback: Minisforum’s after-sales support has been inconsistent. If you have a hardware defect, getting it resolved can take longer than with Intel or established brands. That’s a real consideration for something you’re relying on 24/7.
Best for: Proxmox with VM network segmentation needs, three-disk NVMe setups, anyone who wants dual 2.5GbE without add-ons.
Not for: Hardware transcoding at scale, anyone who needs the best video decode support, or situations where vendor support reliability matters.

Intel NUC 13 Pro (Intel Core i5-1340P)
Approximate CAD price: $650–$780 (bare kit, add your own RAM/storage)
Intel’s NUC line has been through some turbulence — Intel sold the NUC business to ASUS in 2023, so the NUC 13 Pro is technically the last Intel-branded generation, though ASUS continues producing NUC hardware. The NUC 13 Pro uses the i5-1340P, a 12-core (4P+8E) Raptor Lake chip.
Idle power is 8–12W at the wall — competitive with the N100 machines for a much more capable processor. Intel’s efficiency cores do real work here in light load scenarios.
RAM support goes to 64GB DDR4 (not DDR5 — two SO-DIMM slots). DDR4 at 64GB is still plenty, and DDR4 is cheaper right now than DDR5, so your memory budget goes further.
Storage: two M.2 2280 NVMe slots. Standard.
The NUC 13 Pro has a single 2.5GbE port (Intel I226-V — the improved revision, fewer errata than the I225-V). There’s a Thunderbolt 4 port if you want to add a 10GbE adapter, but that’s extra cost.
Where the NUC 13 Pro genuinely shines is Linux compatibility and IOMMU support. Intel’s platform virtualization stack on this generation is mature. IOMMU groups are clean and well-separated. PCIe passthrough works reliably. If you’re doing anything that requires stable, well-tested virtualization support, Intel’s platform is still the reference point.
Hardware transcoding via Intel QuickSync is excellent on the i5-1340P — better than the N100, competitive with or better than AMD’s iGPU for broad codec support including AV1 encode.
Drawback: Price-to-performance isn’t great. You’re paying an Intel brand premium. The Beelink SER7 matches or exceeds it in raw compute for less money. The NUC 13 Pro’s value is in its reliability, build quality, and platform maturity — which matters in a server context, but isn’t free.
Best for: Proxmox users who want the most stable virtualization platform, Jellyfin/Plex servers needing broad transcoding support, or anyone running a production-adjacent homelab where reliability trumps cost.
Not for: Budget-conscious builds, dual-NIC requirements, or pure performance-per-dollar comparisons.

GMKtec NucBox K8 (Intel Core Ultra 5 125H)
Approximate CAD price: $580–$680 (16GB/512GB config)
The NucBox K8 is GMKtec’s push into higher-end mini PC territory, using Intel’s Meteor Lake Core Ultra 5 125H — a 14-core (4P+8E+2LP-E) chip with Intel Arc integrated graphics. This is a notably different architecture from the older NUC 13.
Idle power is 10–14W at the wall. The additional low-power efficiency cores help keep idle consumption reasonable.
RAM support: up to 96GB DDR5 across two SO-DIMM slots. Generous.
Storage: two M.2 2280 NVMe slots. No third slot.
The K8 has a single 2.5GbE port and one additional 1GbE port — so technically dual NIC, though the asymmetry means it’s less useful for symmetric traffic scenarios than dual 2.5GbE.
Intel Arc integrated graphics means hardware transcoding support is broad and includes AV1 encode — useful if you’re running a media server with modern content.
Honest concern: GMKtec is the newest brand in this lineup, and the NucBox K8 is a relatively recent product. Linux compatibility is generally functional, but driver support for the Meteor Lake platform is still maturing in some distributions. Proxmox VE installs, but you may need a newer kernel than the default Proxmox ships with for full hardware support. IOMMU support has been reported as functional but less thoroughly tested in the homelab community than the older platforms.
Drawback: GMKtec’s warranty and support track record is short — there simply isn’t enough history to know how they handle failures on a 3-year-old unit. Also, the K8’s BIOS update process has been reported as clunky by some users.
Best for: Media server builds that benefit from Arc’s transcoding, users who want high RAM headroom at a mid-range price, Meteor Lake enthusiasts willing to accept some platform immaturity.
Not for: Rock-solid stability requirements, users who need proven long-term Linux support, anyone not comfortable occasionally fiddling with kernel versions.

Which One Should You Buy?
Lightweight always-on server / router / Home Assistant: Beelink EQ12. The 16GB RAM limit is real, but for LXC containers and a router VM the N100 is plenty, and 6W idle is hard to argue with at $230 CAD.
Full Proxmox homelab with multiple VMs: Beelink SER7. The 7840HS gives you strong compute, up to 96GB RAM, and proper IOMMU support. It’s the best overall value in this list for serious VM workloads.
Network-intensive homelab or three-disk storage setup: Minisforum UM773 Lite. Dual 2.5GbE and three NVMe slots are genuinely differentiated features. Just update the BIOS before you build anything on it.
Maximum reliability and proven platform: Intel NUC 13 Pro. You’re paying a premium, but the NUC platform’s Linux and virtualization support is the most battle-tested in this group.
Media server focus with modern codec support: GMKtec NucBox K8 or Beelink SER7. If AV1 encode matters, the K8’s Arc graphics have an edge. If you want a safer overall platform, the SER7’s 7840HS is more proven.
The days of needing a full tower for a capable homelab are well behind us. Any of these machines will run Proxmox — just match the specific machine to what you’re actually planning to run on it.
