Computer Case Help

[Pebble713]

My boyfriend needs a computer that he can hook up to the cutting machine in his garage. The machine itself accumulates a lot of saw dust. Does anyone know of a case that has minimal vents so saw dust doesn't accumulate inside? Small/Midsize preferably, and noy too expensive? Doesnt have to look great at all, like i said this is going into a garage.
