Look at the bright side - there’s gonna be shitloads of not that old enterprise hardware on the market.
During the rise of work from home the last few years, my wife needed a home desktop setup. I picked up a used Dell micro for like $200, installed 10 and we were off. She basically just needed an RDP connection so nothing special.
If she needed to continue past when 10 was supported I’d just throw Fedora on there and go through FreeRDP.
I’ve got another micro running some VMs on Proxmox. I love these things.
