Hardware

The short answer: Reuse a suitable computer before buying another one. Choose a compact mini PC when space and noise matter and you do not need many full VMs or internal drives. Compare an expandable used business PC when you need more VM headroom, several local drives, a PCIe card, or a flexible upgrade path. Check the exact model and configuration before buying; a chassis category alone cannot guarantee capacity, noise, or compatibility. ...

For an expandable Proxmox host, shortlist the GMKtec K8 Plus if you need its dual Ethernet and OCuLink. At the checked prices, its $919.99 complete 32 GB / 1 TB kit costs less than our $1,151.96 example barebone build. Choose the Beelink EQ14 N150 for a small container lab, or the Minisforum MS-01 when 10GbE and a PCIe card are actual requirements. The Beelink SER8 is an alternative when one Ethernet port is enough, subject to finding a suitable US offer. ...

Evidence note: This is a research-backed analysis of the GMKtec K8 Plus as a Proxmox host. It combines GMKtec’s system specifications , AMD’s Ryzen 7 8845HS specifications , Proxmox documentation, and attributable owner reports. It is not a first-hand RunAHomeLab hardware benchmark. Community reports identify possible failure modes but do not prove that every unit is affected. See the research methodology .

How this guide was built: this is a reference configuration based on current specifications, pricing, and reports from people running similar systems. It is not presented as a long-term benchmark of a machine we personally tested. After publishing the first version, we asked the r/homelab community what this build could realistically handle and where it would fail first. This update incorporates the useful patterns from that discussion while keeping individual reports clearly labeled as anecdotal. ...
