Weird and even evil question, but I have a graphite 600 mhz iMac, it is about 3 years old and makes the loudest most obnoxious noise, and apparently it has no fan.........anyway I have a 4 year replacement warranty with the store that I purchased it at. So now I would like to break it, to the point where it can never be repaired so that I can get a new one. Can anyone please tell me how to go about this procedure without making it obvious, otherwise I wont get my new iMac. Please help! :?
