Are you familiar with the G71GX? Just drilling holes in the case lowered it more than 6 degrees.
It's a really horribly cooled system. A Core 2 Duo and a GTX260M with nothing more than a 30mm blower fan.
And yeah, thanks. I saw that link. Looking for something that rivals the NZXT in terms of design. The CPU and gpu are within an inch of each other (99% of the heat) and are located Center-Back. As I recall reading, the Zallman had it near the center.
I plan on using copper heatsinks in addition to the case mod and the cooler. Individually, each of these things might only knock it down a few degrees, but combined it could be significant. (Not to mention 6 degree drop is quite a bit.)
