I know that the ideal thing to do is to put to put fans in the bottom front and fans in the top back. Now I just have a quaffle with this. Wouldn't the intake fans in the front be recyclying hot air. I mean there are holes for air intake but what air would the fan intake, it would be sucking air from the inside of the face plate? -discuss

well there should be holes in the bottom front. For my case, the front panel is hollow, with vents all around. The intake fan then sucks air through the chassis hole and gets air from this hollow place. The air thus comes from all over the front of the case (mostly from the bottom of the case...since the case has legs). Even if it weren't sucking enough cool air, it will still help dissipate the heat. It blows the air toward the rear, where the hot air can rise and be pushed out of the exhaust fans. Thus air is always moving, rather than staying stale and in one place (and thus increasing in heat). Remember, all cases aren't built the same...maybe you're concerned because your case was designed poorly?

My case doesn't have any holes at the front, the two intake fans I have draw the air in from UNDERNEATH the case, as a large opening (big enough to stick your fingers right in) runs across the case. Unfortunatly the legs aren't that high, and since my computer sits on carpet I had to build some new legs for it so it will be raised off the ground.

Why not sit the base of your case on a bit of thin plywood that's been cut to match the dimentions of the bottom of your case? This will give your case better access to cool air by eliminating the space the carpet's pile would be. Clear plexiglass or even regular window glass with it's edges smoothed will work if seeing the floor under the case is a sticking point.

I have a very poor case, I mean, decent size but I had to cut all the holes for the fans by myself =( I cutted a square window on the bottom of the front bezel and put a thin metal grille in it and then behind the bezel I cut a 120mm hole for my intake fan, ehich now delivers a full 74 CFM =) After that I cut out a 80mm hole at the back of the case for the exhaust fan and last a 80mm blowhole on top of the case, now my baby keeps running coooooooooool!!!

What tools do you use to cut case metal walls?
