What is considered the cheapest mini pc for linux/emulation?

In this day and age with inflation and scalpers, what are some smaller maybe even mini computers that can handle a linux desktop and some emulation or light gaming and light tasks?

I know about raspberry pi but im preparing to use mine as a nas so its in use for that and i dont want to get another pi because inflation.

What can i do or use then? What would you advise to look out for?
