Last but not least, I have 4u rackmount cases with am3 boards capable of housing 4+ gpus. Rackable switches (16 and 24 port). Lots that can be done with the hardware I am wanting to let go. Let me know what you are interested in. PS. Systems are not limited to AMD or ATI.
Do you have pics of the 4u 4+ gpu rackmount cases? What MFG/model of cases are these? i am very interested.
I can take pics of the actual units if anyone is paranoid, but this ebay link is the exact unit in question. The unit has no problem houseing 2 PSUs, 4 5830 or 5970 gpus, fan housings dirrectly behind the gpu to cool. If you toss in one of the 130cfm fans you see in the goods section for the last 6mo, these work amazing. I had some issues mounting 4x xfx 5770s in them due to the heat desing of the cards. That was the only issue.
