anyone use an Alienware area 51 7500 or other Alienware for trading? http://www.alienware.com/product_de....aspx?SysCode=PC-AREA51-7500-R4&SubCode=SKU-B Are these things loud? one thing that bugs me is the PC noise on my current dell. however, I also am looking around for a quad core with the new Nvidia 8800GTX card. the cooling systems for both would tend to make a PC louder. anyone have a good rec for a quiet quad core? do Alienware's accoustic dampening and liquid cooling system make it quieter? Thanks in advance.
