but more powerful so it can run more, like a high end console built into the back of a wall mounted flat screen, but now I feel guilty for derailing the OP's thread, oops

So get a little Beelink or NUC, mount to the back of the TV.

All-in-one PC is also very much a thing.

Apple iMac is perhaps the most well known all-in-one PC but there are actually far more of them.
