Building a Multi-Node Proxmox Cluster on Mini PCs: 2026 Hardware Guide
Mini PCs in 2026 are powerful enough to run a real Proxmox cluster — three nodes for proper quorum, with HA failover and shared storage, all under €1500 total and pulling less power than a single tower workstation. This is a practical hardware and software guide based on a year of running this setup at home: what to buy, how to network it, where Ceph makes sense (and where it really does not), and the operational lessons learned from real failures....
