    What you're looking for is called a PCIe riser card. They come in various lane configurations and lengths.

    For a nMP
    Search Google Akitio & egpu and you shall find.

    For a cMP
    PCIe expansion costs for x8 or x16 connections are well above $300. A single x16 riser with 2 x16 slots behind a PCIe switch is around $130.

    For the most informative / passionate response:
    Seek the one known as MacVidCards

    No problem. I used a small x4 riser in order to run two double slot GFX cards in the x16 slots, allowing me to mount my Apricorn Velocity x2 card in the HD Bay 4 area and keep my USB 3.0 card installed.

    I've seen people go external like you're intending, on the Xserve systems I think, but it's not something I've done. I imagine you'll want to make sure you mitigate the risk of possible ESD damage for any exposed parts. Good luck, post a pic when you're done!

    Here is what i did so far without any riser gtx550ti gtx770 and radeon 5770. I removed 2 HD trays to fit 550ti and i am planing to reroute one HD with Sata Male to Female extension cable to where dvd burner was i will also have a power supply in there to power 770

    Only problem that i might have is heat thinking of adding a extra fan in the back of the cards ot drill a hole and attache the fan on the doors that come off the mac pro directly blowing in to the cards. does the fan blow air in to out?

    PS i dont think i need Sata Male to Female extension cable since dvd has them all ready.

    thanks
