Best Mini PCs for a Homelab in 2026: MS-01, NUC, and the Used SFF Sweet Spot

Q: What is the best mini PC for a homelab in 2026?

For most homelabbers, the Minisforum MS-01 with an i5-12600H is the best new buy at ~$423 barebone — dual SFP+ 10GbE and dual 2.5GbE NICs in one box. For lower idle power without 10GbE, the ASUS NUC 14 Pro+ wins. For under $200, a used Dell OptiPlex 7060 Micro or HP EliteDesk 800 G4 Mini is the value pick.

Q: Is the Minisforum MS-01 still worth buying in 2026?

Yes. The MS-01 launched in early 2024 and the networking spec — two SFP+ 10Gbps plus two 2.5GbE ports at $423 barebone — has not been matched at that price point. The i5-12600H is still a capable hypervisor CPU. If 10GbE is on your shortlist, the MS-01 remains the recommendation.

Q: How much idle power does a mini PC actually draw?

Modern x86 mini PCs draw 7–30W at idle, measured at the wall, depending on chassis, NIC count, and storage. ASUS NUC and Beelink-class boxes land at 8–15W. Multi-NIC machines like the MS-01 idle higher, around 25–29W per third-party measurements, because the SFP+ controllers consume power even with no link.

Q: Can I run Proxmox on a used OptiPlex Micro?

Yes. Any Intel 8th-gen or newer OptiPlex Micro, EliteDesk Mini, or ThinkCentre Tiny supports VT-x and VT-d, which is all Proxmox needs for KVM and PCI passthrough. Add 16–32GB of DDR4 and an NVMe SSD. The catch is the single 1GbE port — fine for one node, limiting if you cluster.

Q: How much RAM do I need for a homelab mini PC?

32GB is the practical minimum for running Proxmox with a few VMs and LXC containers. 64GB is the sweet spot for any serious homelab — Home Assistant, Plex, a couple of databases, monitoring stack. Most current mini PCs cap at 64GB or 96GB DDR5 across two SO-DIMM slots.

Q: Is a mini PC better than an old gaming PC for a homelab?

For 24/7 use, yes. A mini PC idles at 10–30W. An old gaming PC with a discrete GPU and full ATX PSU idles at 60–120W. At U.S. average electricity rates, the gaming PC costs $80–$160 more per year to run. The mini PC pays for itself in saved electricity within two to three years.

TL;DR — What to actually buy

Under $200 (used): HP EliteDesk 800 G4 Mini or Dell OptiPlex 7060 Micro with an i5-8500T. Six cores, 35W TDP, idles low, eBay all day.
$300–$500 new: Minisforum MS-01 (i5-12600H barebone, ~$423). Dual SFP+ 10GbE plus dual 2.5GbE — the only mini PC at this price with that networking.
$700+ new: ASUS NUC 14 Pro+ with Core Ultra 7 155H, or a Geekom A8 if you want AMD. Lower idle than MS-01, no SFP+.
Skip: Anything with a single 1GbE NIC. In 2026 that’s a deal-breaker for a hypervisor host.

The 2026 mini-PC lineup, ranked by what they’re for

Mini PCs aren’t picked like desktops. They run 24/7, so idle wattage matters more than peak performance. They host VMs and LXC containers, so RAM ceiling and NIC count matter more than single-thread benchmarks. Most ship as barebones — no RAM, no SSD — so the sticker price is the start of the bill, not the end. The shortlist below is five real options: three new, two used.

Minisforum MS-01 — the networking pick

The MS-01 broke the mini-PC pattern. Two 10Gbps SFP+ ports, two 2.5GbE RJ45 ports, three M.2 NVMe slots, U.2 support, and a half-height PCIe x16 slot — in a chassis you can hide behind a monitor (Minisforum). The networking spec is still unmatched at the $423 entry point (ServeTheHome forums).

CPU options run from i5-12600H to i9-13900H. The i5 barebone is what most people want. Power lands around 27W idle in VirtualizationHowto’s measured configuration, with peaks near 120W during simultaneous VM boot. Not great. Not terrible. The networking earns the watts. If you’ve read the first-homelab guide, you’ve seen this pick before. It still wins for 2026.

Best for: Anyone running pfSense or OPNsense as a VM, anyone moving NAS traffic between nodes, anyone who wants real network virtualization without buying a separate switch and second box.

ASUS NUC 14 Pro and Pro+ — the NUC torch keeps burning

Intel sold the NUC line to ASUS in 2023, and ASUS has actually shipped follow-up generations on schedule. The NUC 14 Pro+ runs Core Ultra 5/7/9 ARL-HX-class processors, supports 96GB DDR5-5600 across two SODIMM slots, ships with a 2.5GbE i226 NIC, and uses dual Thunderbolt 4 (ASUS NUC 14 Pro Plus tech specs). The base NUC 14 Pro caps at 48GB and uses a Core Ultra or Core 3 processor in a slightly smaller chassis (ASUS NUC 14 Pro).

What you get over the MS-01: lower idle power. ServeTheHome measured 8–9W idle on the NUC 14 Pro under load testing, with peaks around 88W. Better thermal headroom and tool-less serviceability come with the territory.

The trade is SFP+. A single 2.5GbE port is enough for most workloads, but if you wanted dual NICs for a router VM, you’re using Thunderbolt-to-2.5GbE adapters or shopping elsewhere.

Best for: A quiet, low-idle Proxmox host that runs a dozen LXC containers and a handful of VMs without making your office sound like a hair dryer.

Geekom A8 / A8 Max — the AMD compromise

If you want AMD in a NUC-class chassis, the Geekom A8 ships with a Ryzen 9 8945HS or Ryzen 7 8745HS, dual SODIMM up to 64GB DDR5-5600, USB4, 2.5GbE via a Realtek RTL8125BG, and a single M.2 2280 NVMe slot (CNX Software A8 review). Beelink’s SER8 is the closer comparison on idle power, but the A8 is the easier RAM upgrade path and the more honest spec sheet.

The Realtek 2.5GbE NIC is the one footnote here. It works, but Intel i226 is the part you actually want for a hypervisor — driver maturity matters, and Realtek 2.5GbE chips have a history of needing r8125-dkms or vendor-out-of-tree modules on Linux. Plan for thirty minutes of friction.

Best for: AMD-curious homelabbers who want strong multi-core performance and don’t need 10GbE.

The used SFF sweet spot — OptiPlex / EliteDesk / ThinkCentre Tiny

This is where the math gets fun. A Dell OptiPlex 7060 Micro or HP EliteDesk 800 G4 Mini with an i5-8500T (six cores, 35W TDP) goes for $130–$180 on eBay in 2026. The OptiPlex 7060 Micro supports up to 32GB DDR4 across two SO-DIMM slots plus one M.2 NVMe (icecat datasheet, PCLiquidations). The Lenovo ThinkCentre M720q Tiny is the third option — same 8th-gen Intel platform, slightly different I/O (Newegg listing).

You give up DDR5, 2.5GbE, and modern USB4. You get six real cores, a chassis engineered for office reliability, and an under-$200 entry point that lets you build a three-node cluster for the price of one MS-01 barebone. The honest weakness: gigabit ethernet. For a single-node Proxmox host running a few self-hosted apps, 1GbE is fine. Cluster traffic between nodes wants a USB 2.5GbE dongle.

Best for: Cluster-curious homelabbers, the “what does Proxmox feel like” crowd, anyone who wants three nodes for HA testing without spending $1,500.

What’s missing on purpose

No N100/N305 micro PCs. Fine for a Pi-hole replacement; you’ll outgrow the single-channel memory in three months. No Raspberry Pi 5 — different category. Everything in this article is x86-64 with KVM virtualization and 64GB+ RAM ceilings.

Idle figures are the published or third-party-measured numbers from the sources cited above. The next table is what LK Wood IV measures himself.

Idle wattage — measured at the wall

Wall-measured idle is the only number that matters for a 24/7 box. Everything below is a slot for LK Wood IV’s own Kill-A-Watt readings on whatever he’s currently running. Don’t trust manufacturer “TDP” numbers for idle — they describe peak package draw, not what the system actually pulls sitting at the Proxmox login screen.

Model	LK’s measured idle	Configuration	Notes
Minisforum MS-01	see operator notes	see operator notes	see operator notes
ASUS NUC 14 Pro / Pro+	see operator notes	see operator notes	see operator notes

Until those cells fill in with real readings from the lab, treat the published numbers in the previous section as upper-bound estimates. Different RAM configurations, different NVMe firmware, and different BIOS power-management defaults can swing wall idle by 5–8W on the same chassis.

Top picks by budget tier

Under $200 (used) — Dell OptiPlex 7060 Micro or HP EliteDesk 800 G4 Mini

For $130–$180 on eBay: six real cores at 35W TDP, 16–32GB DDR4, a chassis over-engineered for corporate desks. The verdict is an OptiPlex 7060 Micro with i5-8500T and 16GB DDR4 added at home. A 500GB NVMe puts you under $250 all-in. Pair two and you’ve got a small Proxmox cluster to learn live migration on — the cheapest legitimate way to see what real infrastructure feels like.

$300–$500 (new) — Minisforum MS-01 (i5-12600H)

The networking is the entire argument. $423 for a barebone with dual SFP+ 10GbE plus dual 2.5GbE is not a price that exists anywhere else. Add 32GB of DDR5 SO-DIMMs (~~$90), a 1TB NVMe (~~$70), and you’re at ~$580 total for a node that out-networks small business gear from five years ago.

If you’re going to run Proxmox versus TrueNAS or Unraid as your hypervisor stack, the MS-01’s NICs let you separate management, VM, and storage traffic on physical interfaces — which is a real architectural win, not a benchmark game.

$700+ (new) — ASUS NUC 14 Pro+ with Core Ultra 7 155H

When idle wattage and acoustic profile matter more than dual SFP+, the NUC 14 Pro+ is the recommendation. 96GB RAM ceiling, Core Ultra 7 155H, low-watt steady-state, tool-less serviceability. Pair it with a managed 2.5GbE switch and the box disappears into a bookshelf. If 10GbE on a budget becomes a priority later, Thunderbolt 4 to SFP+ adapters work — don’t expect mini-PCIe magic.

Where to check current prices

Mini-PC pricing moves week to week. Check before you buy:

Minisforum MS-01: Minisforum store and Amazon search “Minisforum MS-01”
ASUS NUC 14 Pro / Pro+: ASUS USA and SimplyNUC
Geekom A8: Geekom direct and Amazon
Used OptiPlex / EliteDesk / ThinkCentre Tiny: eBay, ServerSupply, PCLiquidations, r/homelabsales

If the listed price is more than 20% above the bands above, wait a week.

What this hardware should run

The standard stack: Proxmox VE on bare metal, a few LXC containers for lightweight services, one or two VMs for anything that needs its own kernel. The Proxmox mini PC setup guide walks through the install.

A single NVMe boot drive is fine for hypervisor-only use. For bulk storage, the MS-01’s three M.2 slots and the NUC 14 Pro+’s two slots both leave room for a ZFS mirror — but for real capacity, run a separate box per the budget NAS builds guide. A 2.5GbE switch is the realistic minimum in 2026; SFP+ matters once you’re moving VM disks between nodes.
