Well, I posted in the iMac post with joy that my computer has come. But, now that I have it up and running and I sit next to it typing on my iBook it is LOUD. Big time high pitched hum, fan like sound that turns on as soon as I turn on my computer and doesn't go away except when I put it to sleep. This is nothing like the reviews I read or like the 17" model I saw at CompUSA yesterday that had been on for who knows how long. So, what is the correct procedure about getting this thing fixed. I'm afraid I'm not going to have me new iMac very long am I....????
