Query: Expensive, NOISEY! Poor support!

This iMac is one of the worst apples I've ever used. It's way too over-priced, and what's worse is that my iMac has a noisey buzzing helicopter sound to it and the hard drive click and whirr like crazy. I called Apple and since I custom configured it on the phone with them, I can't return it.I've had many many many many problems with my iMac and I would not recommend it to anybody.
