I actually tried it before for my TV PC that I wanted to also use as a miniserver, with gpu pass through and everything. It was painful to get it working properly, was like 30-40% slower. I also had constant problems with USB peripherals not connecting properly, or going in a sleep state and not waking. Many games didn’t work properly.
Then I decided to just buy a cheap second second hand PC and never looked back.
Even basic stuff like operating systems (especially Windows and Android), chatting software, music playback software etc has gotten so terrible. Microsoft constantly adds unnecessary and intrusive features to Windows, Teams needs a supercomputer to perform decently, and every app is now a poorly optimized electron app that tracks everything you do.
