Which case would you use?

[micron]

I have a T-Bird 800@1000 1.85V FOP32-1 Arctic Silver. I have two cases, an old Micron case from a millennia mme (it has no place for a fan in front, one 90mm fan in the rear, and a 90mm fan that I put in the side.), and I also have a Enlight case (not sure which one.) It's got a 80mm fan in front, no place for a fan in rear and the PSU mounts verticaly.). I was thinking of modding the Enlight. I want to make the holes bigger and put two 90mm fans up front, and put a 90mm fan on top directly above the CPU and maybe a rear fan. If I mod the enlight, which case would be better for my setup?

Thanks, micron
