Monster Case: cooling

So I mentioned last post that cooling was the reason for doing this. Maybe justification is a better word. I don't really have a reason, it just sounds like fun.
But since cooling is an issue with this case (1 80mm fan in the back just isn't cutting it...), I should start there. There's a spare 80mm fan to install on the front, no problem. But what about a blowhole? That'd look kinda neat too.
So, if I'm going to cut a blowhole, shouldn't I have a fan to put there too? No such fan in my junk pile. I could've just gone and bought a new fan, but why pay when you can find something instead? Sure enough, I found this:
[picture coming soon]
A 140mm air hockey fan. 110volts chugging out a promised 500cfm. For comparison, a good hairdryer is between 200 and 350 cfm. Computer cases usually run at about 100 cfm. Having this much airflow will probably suck the dust right out too, which means I'll want a filter. No problem.
So this monstrosity of a top-fan got me to thinking. I could do a few things here. Either leave the 80mm in front and the other in back and just let the 140 suck out all the excess up top; put both fans up front, close off the back and suck ALL the air out the top; or get another big fan up front, move the 2 80mm to the rear, and get even more airflow all the way around.
Time for a new front fan.
USB light fan
Hehe.
So this thing is going to sound like a NASA liftoff when I'm gaming, but the extra top and front fans are specifically FOR gaming, and switch on and off outside the case (ghetto-rigged, because I don't feel like rewiring the big boy). That means that I'll only have them on when the music's too loud to hear them anyway. The rest of the time it'll be the standard hum of 2 little fans.
Next lets play with the design.
