Find the right used mini PC for your home server
Ex-office 1-litre PCs (Lenovo ThinkCentre Tiny, Dell OptiPlex Micro, HP EliteDesk Mini) are the cheapest good way into Proxmox, Plex, Jellyfin or Home Assistant. They look alike in listings but differ in the details that matter: NVMe slots, PCIe expansion, second-NIC options, RAM limits and video transcoding. Filter by what you need.
