Mini PC Deep Comparison: Beelink, Minisforum, Topton, and GMKtec for the Homelab

The mini PC has quietly displaced the repurposed desktop and the secondhand enterprise server as the default homelab node for most people. The reasoning is sound: a current-generation mini PC idles at 6–12W, fits in a hand, costs $100–300 depending on the tier, runs Proxmox or any Linux distribution without modification, and outperforms an old Xeon that draws 80W at idle on single-threaded workloads. For a homelab that runs VMs, containers, a NAS stack, or a small Kubernetes cluster without needing GPU compute, mini PCs are the practical choice.

The market is crowded with Chinese brands that are confusingly similar on spec sheets and meaningfully different in practice. This post breaks down what actually matters when choosing between them — NIC quality (the most common reason homelab builds fail), thermal behaviour under sustained load, NVMe slot count, and the specific models worth buying for different use cases.

What Actually Matters

Spec sheets for mini PCs are consistent in what they overstate (graphics performance, “gaming” claims) and what they understate or omit (NIC chipset, thermal throttle behaviour, M.2 slot PCIe version, real idle power). The factors that matter for homelab use:

NIC chipset, not just speed. A 2.5GbE port using an Intel I226-V controller is fundamentally different from one using a Realtek RTL8125. Both advertise “2.5GbE” but Intel NICs have mature, upstream Linux driver support with zero configuration on Proxmox, pfSense, OPNsense, and every mainstream distribution. Realtek NICs have historically had driver issues on Linux — stability problems under sustained load, missing features, and kernel module churn. For a router/firewall build, a Realtek NIC is a real liability. For a Proxmox node running workloads that don’t saturate the NIC, it’s usually fine in practice, but you’re one kernel update away from a bad day.

M.2 slot count and PCIe version. One M.2 slot means you’re choosing between OS/system drive and additional storage. Two slots — especially when the second one is PCIe 4.0 x4 — is a meaningful difference for NAS builds or anything that needs fast local storage.

TDP and sustained power. A processor rated at 28W TDP in a mini PC chassis will thermal throttle if the chassis can’t dissipate heat. The difference between a chip running at its rated TDP and a chip throttling down to 15W under sustained load is significant for Proxmox compilation jobs, transcoding, or ML inference. Chassis size, copper heat pipe count, and fan speed ceiling all determine sustained performance.

RAM upgradeability. Some mini PCs solder the RAM; most use SO-DIMM slots. Soldered 16GB is a dead end for memory-hungry Proxmox workloads. Two SO-DIMM slots supporting DDR5 and upgradeable to 64GB or 96GB changes the calculus entirely.

Idle power, not TDP. For a machine that runs 24/7 under light load, the idle power figure is what drives your electricity bill. A Ryzen 7 7840HS in a mini PC idles at ~8W under a light Proxmox load. An old Xeon E5 server with the same workload idles at 80W+. Over a year, that difference is real money.

The Brands

Beelink

Beelink is the market leader for reliability and mainstream availability. Their products are stocked widely on Amazon (usually with returns-friendly policies), their Linux compatibility is well-documented by the homelab community, and their build quality is consistently adequate — not exceptional, but consistent.

The SER series (AMD Ryzen) and EQ series (Intel N-series) cover the most common homelab tiers. Beelink’s NIC choices tend toward Intel controllers on the dual-NIC models, which is the right call.

Recommended for: First homelab node, builds where Amazon returns matter, mainstream Proxmox clusters.

Minisforum

Minisforum targets enthusiasts and is the most technically ambitious brand in the segment. They ship features that don’t exist elsewhere at this price: OCuLink ports for external GPU, PCIe x16 internal slots, 10GbE NICs, 2U rack-mount form factors, and true desktop GPUs in compact chassis. Their AtomMan line with RTX 5060 is a legitimate small AI inference node.

Quality control is less consistent than Beelink, and customer support is hit-or-miss for international buyers. The community around Minisforum is active on Reddit and their own forums, which compensates partly for the support gap.

Recommended for: Builds that need 10GbE, OCuLink for GPU attachment, rack-mount form factor, or serious compute in a small footprint.

Topton

Topton sits in a different category. They sell primarily through AliExpress and focus on industrial/networking mini PCs — boxes with 4, 6, or 8 2.5GbE Intel NIC ports explicitly designed for router/firewall builds. If you want a dedicated OPNsense or pfSense appliance with 4+ Intel NICs, Topton is where you look.

Build quality is no-frills. These are bare-bones boxes without the consumer polish of Beelink or Minisforum. Setup documentation is sparse. But the hardware — especially the multi-NIC Intel controller configurations — is genuinely good for the intended purpose.

Recommended for: Dedicated firewall/router appliances, network lab builds, multi-NIC requirements.

GMKtec

GMKtec competes aggressively on price, frequently undercutting Beelink by $30–50 for equivalent specs on paper. RAM and storage are generally user-serviceable, which is a legitimate advantage. Their NucBox series covers budget Intel N-series builds.

The honest caveat: customer support is minimal. GMKtec assumes you’re technically capable and will troubleshoot your own issues, rely on community forums, or handle warranty claims through Amazon. For homelab builders comfortable with self-support, this is acceptable. For anyone who expects vendor support, it’s a risk.

Recommended for: Budget-first builds, quantity purchases where per-unit cost matters, technically confident builders.

Model Comparison: 2026 Homelab Tiers

Budget tier: ~$100–180 (Intel N-series)

The Beelink EQ14 is the standout at this tier. Intel N150 (Twin Lake, late 2024) is a genuine improvement over the N100: 15% more single-thread performance, improved efficiency, and the same thermal envelope. The dual Intel I226-V NICs are the key differentiator — every homelab guide that recommends mini PCs for Proxmox or OPNsense points at Intel NICs for a reason. At under $220, the EQ14 is the default recommendation for a first homelab node or a low-power always-on service host.

The Topton 4-NIC box is for a different use case: OPNsense/pfSense dedicated appliance with multiple physical network segments. It is not a general-purpose compute node.

Mid tier: ~$250–400 (AMD Ryzen 7 / Intel Core Ultra)

The Beelink SER8 with the Ryzen 7 8845HS is the mainstream choice. It handles a 10–15 VM Proxmox cluster with room to spare, supports up to 96GB DDR5, and has two PCIe 4.0 NVMe slots for a fast OS drive plus a large data drive. AMD’s iGPU handles light transcoding. Real idle on a Proxmox host with a few lightweight VMs: around 10–12W.

The Minisforum UM890 Pro adds 10–15% more compute headroom with the 8945HS but runs warmer and draws more power. Worth it if you’re running CPU-intensive workloads; unnecessary for most homelab use.

NIC note: both use Realtek 2.5GbE on some board revisions. Verify the specific NIC chipset before purchasing if you’re building an OPNsense node — this detail changes between production runs.

Performance tier: ~$400–700 (AI inference, GPU, high I/O)

The Minisforum MS-01 deserves special attention for homelab Kubernetes and NAS builds. It ships with two 10GbE SFP+ ports and two 2.5GbE ports — enough network bandwidth for a legitimate small cluster. It’s the one mini PC where the networking genuinely matches enterprise hardware. At ~$500–600, it’s expensive for a mini PC but cheap for 10GbE node hardware.

The AtomMan line is where Minisforum gets interesting for AI workloads. The Ryzen AI Max+ processor with its integrated Radeon 890M iGPU can run 7B–13B parameter LLMs at acceptable inference speeds. The AtomMan X1 with a discrete RTX 5060 is a genuinely capable inference node in a form factor that fits on a desk.

Proxmox-Specific Considerations

IOMMU groups. Mini PCs generally have poor IOMMU group separation — the PCIe lanes available in a compact chassis don’t allow the isolation that full-size servers provide. PCI passthrough of NICs is possible but requires verifying IOMMU support at the BIOS level (usually under “AMD-Vi” or “VT-d”). The Beelink and Minisforum BIOS settings for IOMMU vary by model; the community wiki pages for each model are worth reading before purchase if PCIe passthrough is a requirement.

Proxmox network setup. On a typical Beelink EQ14 or SER8, Proxmox sees both NICs out of the box with no additional driver installation. The standard setup:

# /etc/network/interfaces on Proxmox
auto lo
iface lo inet loopback

auto enp1s0
iface enp1s0 inet manual

auto vmbr0
iface vmbr0 inet static
    address 192.168.1.50/24
    gateway 192.168.1.1
    dns-nameservers 1.1.1.1
    bridge-ports enp1s0
    bridge-stp off
    bridge-fd 0

The second NIC can be dedicated to storage traffic, a separate VLAN, or a dedicated Ceph or NFS network in a multi-node cluster.

Thermal throttling under Proxmox. Mini PCs running sustained VM workloads can hit thermal limits. Monitor with:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11

# CPU temperature
cat /sys/class/thermal/thermal_zone*/temp

# Watch for throttling events
dmesg | grep -i "thermal\|throttl"

# More detail via turbostat
turbostat --interval 5

# Or via sensors
apt install lm-sensors && sensors

If a mini PC runs at 90°C+ under load and you’re seeing throttle events, repasting the CPU with quality thermal compound (Noctua NT-H1, Thermal Grizzly Kryonaut) is the first intervention. Mini PC thermal paste quality from factory is variable; some units ship with adequate paste, others with paste that has already dried out.

Practical Build Patterns

Single-node homelab (1–2 services, low power)

Beelink EQ14 — $180, 16GB DDR4, dual Intel 2.5GbE, ~6W idle. Run everything in Docker Compose. Adequate for a personal homelab with Plex, Home Assistant, a VPN server, and a few self-hosted apps.

Proxmox cluster node

Beelink SER8 or GMKtec K8 Plus — $300–350, 32–64GB DDR5, PCIe 4.0 NVMe. Three of these form a Proxmox HA cluster for under $1,000 with a combined 96–192GB RAM and ~30W cluster idle power.

Dedicated router/firewall

Topton 4-NIC N6005 — $120–150, 4× Intel 2.5GbE. Install OPNsense, configure VLANs and firewall rules. More capable than a consumer router, much cheaper than enterprise firewall hardware.

NAS + compute combined

Minisforum MS-01 — $500–600, 10GbE SFP+, slots for 2× NVMe + optional 2.5" drives. Runs TrueNAS SCALE or Proxmox with a TrueNAS VM, serving storage over 10GbE to the rest of the homelab.

Edge AI inference node

Minisforum AtomMan G1 Pro or AtomMan X1 — $500–700. Runs Ollama with 13B–32B models. The iGPU variant handles LLM inference via ROCm; the discrete GPU variant is faster and simpler to configure with CUDA.
