Newbie question.. I am seriosuly thinking of building my own box concidering the recent price drop on the Q6600 to around $500. But with all the issues of cooling, I was thinking why not just buy an external box and mount the power supply in it? I am guessing a good 700w PS produces a good amount of heat. Is this not practicle?? I am looking at installing the system in a closet anyway with wireless keyboard/mouse on desk. Looking for a clean install. Thanks for your help.
