If you need an example of a positive pressure case, which is what mine is, here's what mine looks like.
I have a fan controller however which runs my two front fans at a low speed, and the exhaust fans at a slightly faster speed. The 12cm's are also high CFM, so they transfer a lot of air flow, and the large 25cm fan is a low RPM, low CFM fan, I got the side panel mainly to see if it would help keep my motherboard cool (it does, but just marginally).
The case in question is a Thermaltake Armor, first generation. That upper left 9cm fan is where my two raptors sit in their little cage, so they get some direct exhaust lovin action.
I only put the video card on there because it's a dual slot card and sometimes I crank it up during long gaming sessions, so that will impact the lower case air flow.
