I just bought it about 15 months ago, It had no cracks that I know of. The computer is only 2 months old. I was in the middle of the game, and heard a crack. I thought someone threw a rock at my window. I searched the house and found nothing. I went back to the game, and it was frozen. So I popped the disk drive open to reset the game, and found only shards of plastic. I thought this could only happin on Mythbusters. But sure as im sitting here, it just did. I dont want to open the computer up and get the rest of the chunks out yet caust its still under warrenty. What the hell?
