the case comes with one 120mm installed in the rear
the case (from the pics) can take
one fan up front with holes for 80mm/ 92mm,/120mm/140mm
two 120mm on the sides
one fan up top looks like holes for 92mm/140mm
FYI, the PSU that comes with that case is barely enough for an office build. if you plan on building a gaming PC, get a solid PSU
450 watts isn't enough to power 269 watts? This is what it's for: http://pcpartpicker.com/p/2at8K
Would having two 120mm fans on the sides be the best choice?
a solid 400w PSU will power your set up, the PSU that comes with that case couldn't hit 350w without a spark show
one fan as a front intake and one as a back exhaust will do the job for your set up
What are you basing the imploding of the PSU on? I don't understand what you mean a 450 watt can only run 350.
Is this better?
