A final follow-up and I will mark this thread solved.
I have delivered the computer to the buyer, I spent 9 hours at their house migrating data, installing programs they like, setup and testing the printer, and testing the joystick with Flight Simulator
Since the HD finished search indexing it is much quieter, plus I put the side back on the case. It does seem the noise was just the intense indexing it was doing at initial set-up and now it isn't really noticable.
With the heat from the HD, the quad cores, and the HD4850 this will make a nice foot warmer for his wife in the winter months. I have pretty good circulation with the case mod so it rolls out the back.
Thanks for all who posted or laughed.
Hmmm, clifford it doesn't give me the option to mark it solved, is this because I'm the last poster? If you could please mark it SOLVED.
