Hmmm I love my DeWalt power tools so much I fondle them late at night when nobody's around *chimp sounds* ... and even I wouldn't drill on a PC case (especially an antec case).
...although I did use a rubber mallet on a case that was damaged during shipping.
Oh, and never let a woman near a barbeque either. Once I left my wife watching the steaks for a few minutes. Came back and my brand new grill was literally melting, with the fire burning down the gas line towards the propane tank. Could've easily taken the whole house with it.
