best places to put fans...
1.bottom front in conjunction with a top rear
2.bottom front in conjunction with top middle of case
3.(looking from the front) left side, middle, as close to over the cpu/agp card as you can get it...larger fan helps...in conjunction with a rear exhaust, or top exhaust.
i think that when you have it blowing right over the video card, and the cpu, you get better video card cooling, and cpu cooling, and there will be less "forward" noise because the fan is not on the front of the case.
and i think that a "chimney" fan will help a lot.
think about it this way...heat moves up. the top of the case is the logical place for most applications.
a thing you might look into when you are adding fans is fan control...like a bay bus...
they help control the noise, and make it so that when you are running your computer on days where it is cold in your room, or you dont really need the fans, you can turn them off, to conserve energy, and to make the computer much quieter...
also, look into some large, low noise fans.
have fun modding, and remember that once you start, you will become hooked, and next thing you know, you will be trying out a bunch of crazy stuff....
take your time, measure 10 times, but once, and GET THE RIGHT TOOLS!
a dremel is nice to have for something like this, with a few of those FIBERGLASS REINFORCED cut off wheels. if they are those normal ones, they can EXPLODE, they did to me, after i read about it happening, used it for a while, figured the article was BS, and when i was trying to cut an aluminum post on a rheostat, the wheel exploded, and shot pieces in all directions...oh yeah, that reminds me, wear safety goggles...that will save your eyes.
