Once you get something running proxmox you will fully go down the rabbit hole!
You will be thinking about k8s clusters, DNS and domain management, redundancy & availability, services for this, that and everything!
Before you know it you will have a rack of 8 servers doing various things, 2 UPSs, a standby generator and a backup 5G wan connection!
Or, you know, as much of that as you want.

I designed and implemented a very complex voice system for an old guild. Like 100 people, 8 groups of 15, group leader’s private chat, priority speech all that. It worked so well, and never failed.
This was many many years ago, to be fair.
I wish it’s positional audio was more supported.
