Thanks for the advice! The 16 is probably as overkill as you say, but I’ve come to prefer a larger machine to work on.
I already have Proxmox installed on a secondhand mini-pc (one of those NUC / thin-client like office machines) and it’s been a great way to (re)learn a few things indeed!
I did play it a few weeks ago with some friends, worked flawlessly! (using steam, on fedora, with a Nvidia gpu)
