Operating Systems I current use

I have a proxmox server (Virtualization Server) so I can try out lots of different Operating systems, I current run, Windows 11 Pro(as a Virtual Machine), I have a mac mini (physical) and my main operating system at the moment is CachyOS (as a VM which is an Arch based distro of linux).

I also run various linux distros on Proxmox, inluding Ubuntu, Fedora, Ubuntu Server, I have also tried PopOS and Mint.

Proxmox can be run on an old desktop pc past its prime, and great for testing operating systems, and did I mention its also FREE.
