I run my media server on my gaming PC, you don’t need anything special to do it. I haven’t had any issues gaming online while streaming/downloading either.

The younger generations seem to have no concept of what hardware and software is needed, because most of the companies that sell that stuff are trying to maximize profits and vendor-lock in, which leads them to “teach” their customers bad information. It’s the exact same reason why there are so many people who think they need 64gb or 128gb of ram in their gaming machine.

My arch system runs an arch VM.
