Proxmox
Proxmox is still my go-to because it makes it easy to run a mixed homelab with VMs and LXCs. Restoring backups from my HL15 onto the ZimaCube was fast, and it let me keep my setup flexible while I experimented with things like TrueNAS in a VM.
You'll be taken to Proxmox to complete your purchase.
“So the Zima Cube was ready to fire up, and because I've got such an affinity for Proxmox, that is the OS that I installed on it”
“And the cool thing about having TrueNAS and Plex VMs on the same machine is that all of the data is handled locally via Proxmox and isn't taking up bandwidth on my network, so that's kind of a nice little cherry on top”
“And my ZimaCube Proxmox setup is attached to it via SMB for VM and LXC backups, so it's probably just going to stay on indefinitely”
