I assume you are using pi 4 and/or 5? I would have some 3b+ laying around which don’t see any use nowadays. But can’t quite imagine to build a cluster only made up of these, I think they are too underpowered, unless being used as like a small additional worker node.
And buying new Pi 5 with 16GB of memory would set me back at least 200€ a unit, not including power supply or any case.



Not planning to run nodes as LXC at all. Just using them in my current setup for running services like Wireguard or Jellyfin.
At most I would create VMs for nodes, but still on the fence if I should just go bare metal or proxmox with virtualized nodes (VM).
