Here's the deal. I'm in the process of designing a really unique air-cooled case based around isolation of each component in its own box (one for mobo, one for each hard drive, one for PSU, etc.) What I'd really like to do is place the video card(s) in a separate wind tunnel with 250mm intake and exhaust fans. This means I would need a PCIe extension cable, if such a thing exists. PCI-sig seems to have designed one, but I can't find very many details or a site where it is sold. Does anyone know if PCIe cables really are a possibility and, if so, where I can find one? Any help would be greatly appreciated.
