I swear, and Island can vouch for me as he has experienced it first hand.... My home office is EXTREMELY HOT even with the heat OFF, with 2 computers, Mac Pro Quad-Core, Dell Quad-Core, 2 30" ACD's, 1 24" 2407WFP. I have a 37G aquarium in here as well, I'm sure it adds a little to the heat of the office but still... If you put your hand even close to the 2 30's for instance you will completely and totally not be able to deny the intense HEAT! I have to open windows to remedy this. The room is about 12' x 15' and it is this hot w/o running lights, and heat turned very low. 64 degrees, (we're in Connecticut so it's still cold out). Just wondered if anyone else has noticed this or been effected by it... Thank you!
