I'm going to get the Thermaltake Armor (Should arrive next Thursday =D), and was wondering if I could add another 120mm fan in the front. It comes with 4 fans, one of them in the front. But, I saw on the thermaltake site, the front fan is relocatable. I was wondering if I could add a 120mm/90mm fan in the front to increase intake. If so, what fan should I get? I searched and, the "FM121" came up as a good one. But, I'm getting a PC&Power 510 (650 W) power supply. How do I hook up a 120mm fan, and should the 120mm fan be a sleeve, ball, etc.? Thanks for your help.
