Ok, so 2 GPUs in there. Have you tried 4 or is that not possible for some reason?

I have plenty of other hardware floating around here so no problem on hooking it all up.

Thank you for the image.

I have not, but it is technically possible. the PSU is the double 1100W with the GPU enablement kit. Up to 4x PCI-x 16x full speed. Also up to 1.5TB RAM, and 8x 3.5" HDD or 16x 2.5". I didn't go this far though ($$$...)
