Why not think outside the box? Buy a nice little piece of veneered plywood or something similar and wall mount it.
Oh no. PLEASE no. The dust... Too much dust and grubby fingers/paws and everything that is floating around. That's why computers have filters.
What kind of filter are you using? Also, wasn't really entirely serious with my post. But why wouldn't you be able to put a filter on a wall mounted pc, just waterblock everything and filter the radiator for cooling.
Ok I'm gonna use techpowerup. By the way, what was that silliconlottery cpu thing that u shoes me? How does that work?
