in or out?
 

what is best, to have all fans in, half in and half out or all out? there is one helluva discoussion about that on www.nordichardware.om, but i thaught i would ask here. personaly i think that you should have all fans at the back blowing in, note that they should be poistioned high above ground to avoid dust, and fans down in the front to blow out. more in than out to avoid low pressure in case that draws dust into all samll cracks and holes in the casing.
what do u think? give me your opinion!

Equal in and out, perhaps slightly more in to stop dust, but not much.

In at the bottom and out at the top to help get hot air out. Use filters to stop dust on intakes. I prefer not to have air blowing on my feet so I like in at the front out at the back. So pretty much opposite to you. ;']

most people say a little bit more in than out, I generally agree with that. The one time I won't always say this is when you are watercooling, it can be good to have no fans on the rad, and every fan in your case blowing in, with all other exits sealed. So all the air needs to go through the radiator.
