You're going to want a bigger tower if you're getting the 8800gt, not saying it won't fit but it will be pretty cramped expecially if you ahve a heat sink etc, I mean my friend has a Xion mid tower and it fits fine but his heat sink is touching both his psu and his gpu so...just depends on what you want. As well watch out for the artic cooler 7, because from what I read, it isn't compatible with a lot of core 2 duo processors. I would personally get a Zalman, which for mid range is about 40-50 bucks, and for one of the best its about 60...but depends on what you want
