How does that work for you? Does it stop hot psu air rising into the case?

How my setup at the moment then? I have 2 intake on the sides, and 1 exhaust out the back behind the cpu. This way, cool air is blown straight onto the gpu and nb, removed from the cpu, leaving the rest to come slowly out the top, and warm my feet. All i wonder about is the warm air which gets dispersed on the underside of the video card.

I dont currently have anything in the front, so the air from the harddrives doesnt go into the case. It just sort of goes straight up, around the dvd drive and out the top. Ive gotta say, for such a cheap case, im really loving this cooler master.

for a cheap case its hard to beat imo.

my psu isnt warm so no real heat rises from it, but if it was i guess it would be sucking it out itself.

positive pressure is good, but you need exhaust.
few things on that. air always has aplace to go even without an exhaust fan in a computer case.
your not going to build up that much positive pressuer with axial fans. they are not very efficient and producing pressure. if I remember right it was something like .01psi or something like that for a high high end 5000rpm 120mm fan. axial fans are just very leaky and don't spin to high enough rpms to create any real type of pressure on them.
