Firstly, what type cpu are you planning on running, will you have numerous hard drives setup inside ?
Couple reviews stated pretty decent air-flow , might consider waiting to get everything up and going and monitoring your temps inside to see if the temps warrant modifying the case. I have done a little to (2) cases and unless your a pro- it kinda takes away from the case unless your real good. (with that in mind and I'm guessing theres a 120mm upfront on the bottom sucking in)
* you could - add an 80mm on
top more towards the front of the case and also , depending on your hard drive reply, take out the bottom internal 3.5 (x3) bay and remove it.*[ looking into your case from the window door] place a 80mm all the way in the back on the right about 1 1/2 inches from the front of the case as an additional intake fan. You can get fan dampers & grills at newegg real cheap if you choose to go this way. Its very easy to do this and real easy to make your case look like crap too. *I* would get it all running and think about it awhile before getting the power tools out!
