I'm building a new computer, and am tyring to figure out how many fans to order, adn where i'm going to put them. I'm getting that cheiftec/antec case that almost everyone has, and for fans im getting panaflo L1As (Chose over stealths bc I heard stealths made an annoying buzzing sound). Now keep in mind these dont move too much air (24cfm?), so I may need more fans than normal. I definatly want to put an intake in front the HDs, and two exhaust on the rear of the case. There is also a side spot for a fan, and a place for a front intake below where the hd intake fan will be.

Any advise on weather i should use the bottom intake or not?
Should I use the side spot, and should that be intake or exhaust?
