I took a 20mm Ammo Can from Government Surplus. Cut out a fan blow hole (with Punisher Grill) Then put in a computer tray inside (dremeled out the back tough metal) then put in a side LCD temp panel. I put in a bullet case as the on off button. Had to add exhaust fan through the slots. Had to hang to exhaust fan because it would make LOUD noise from the case resonating. Also built "game chair" our of old medical chair... making it camo colored.
