I currently run Proxmox 8.0.4 on an i5 NUC11 with 32GB of RAM and 1.5TB of SSD storage. There’s a single MySQL VM, and everything else runs as LXC containers — a couple of K3s nodes, Minecraft, Project Zomboid, dnsmasq, Tailscale, Prometheus, Grafana…

The thing runs cool and quiet, and it’s sitting atop my Synology DS420j, next to an APC BVX700LUI-MS.

I’m looking to experiment with Ceph and HA Proxmox, so I might add another NUC and/or a HPE Microserver G10 to my fleet. Keeps the whole setup compact and neat, and I can still run them all off of my existing UPS.
