Many years ago, we had a troubled employee leave work very mad. He was quite furious with his computer and went home for his revolver unbeknownst to us. He came back to work with it and unloaded all six rounds into the system. Each round went through the case and each one missed the drive/motherboard/videocard. So, the system was still working despite the abrupt extra cooling holes. This further incensed him and he went away even madder, but this time in cuffs.
