Sunny Florida, you can keep the midwest!!
I am in the middle of building my new full tower and am laying out my fan locations.I have a 120mm(90+cfm) in front sucking in, a 120mm on the side blowing on the GPU and CPU, a 120mm blowhole and 2 -80mm above the PSU sucking out. I am considering adding an internal 92mm fan(50cfm) between the upper and lower case to help remove the lower case heat. OOps, I also have an Ultimate HD cooler located in the middle for my Deskstar. Any comments good or bad on this setup.

If you have the space, install one of those "slot style" cooler fans. These remove a lot of air from down in the expansion card area, which is usually a dead spot for cooling.

I've got a mid tower setup like this....:

fan, in, lower front of case
fan out, 1/3 of way down from top, back of case
fan out, "slot" type (mounts in open expansion card slot) between my AGP and ethernet cards

my case temps never go more than 5 degrees cel. over room temp.

At some point, I'm gonna get one of those HDD coolers that mounts in a cd-rom bay. I still have an open bay directly in line with my cpu/slocket assy., so I might not even mount the HDD in it, just let it blow straight at the cpu.

I read in a couple of different magazine articles, and a few places on the web, that more exaust fans than intake is the best way to go.

You can pump a ton of cool air in, but if it's not getting OUT as fast as it comes in............

I like your thinking. I am thinking of doing something similiar to my machine. Right now I have the following

1 intake in the lower front
1 blowing out right below the PSU
1 of the HDD coolers (not with the heat sink)
and the power supply fan

I an thinking of adding one fan on the top by the PSU and one blowing out on the side by the CPU.
