Here is the latest one, I call it CrossFlow Extreme. Its made from Perforated alum and CarbonFiber.
Notice the lack of wiring (its all soldered to the back of the mobo (except IDE and Sata)

(DFI please forgive me my transgressions for using an ASUS mobo, it wont happen again)
Here is a shot of the inside

I am using a pair of Hitachi 80gig Laptop Hdds in Raid0, laptop DVD, a pair of XFX 8600GTs in SLI, custom made blocks for the GPUs and a next gen CPU cooler from DangerDen.(thanks Dan)
