Old laptop or mini PC is the way to go.
Old laptop also gives you a screen, keyboard and battery (UPS) which is cool.
I have been explicitly avoiding anything with a battery as I see no reason just to kill it for the sake of doing so.
Maybe I should learn more about power consumption, and maybe things are just a lot better now than they used to be, but running a laptop plugged in 24/7 turned the one I had in college into a pretty useless machine in only a few years.
