    Because i had a spare Nvidia GTX 570 Graphics card and power supply, i built an eGPU setup for my MacBook Pro 13' 2012. The eGPU is connected to the Mac Book Pro via a Thunderbolt 2m cable.

    Thunderbolt to PCI Express: http://www.sonnettech.com/product/echoexpresscard34thunderbolt.html
    PCI-Espress to PCI (important: only PE4L v2.1 supports PCI E 2.0):
    http://www.hwtools.net/Adapter/PE4L V2.1.html

    All parts are PCI Express 2.0 x1 (5 Gbit/s), that's what Thunderbolt 1 supports.

    The case is a Cooler Master Elite 130.

    Some Nvidia driver patching an KEXT editing: http://forum.techinferno.com/implem...ps-tb2-netstor-na211tb-win8-1-osx10-10-a.html and http://maxserve.blogspot.tw/2014/04/how-to-recognize-gpgpu-via-thunderbolt.html

    … and it works! :) Got a signal at the display. OpenGL (Gaming) 561% faster than internal HD 4000 Graphics, GPGPU (OpenCL and CUDA) working. All fine, including playing HD movies from iTunes Store, DVDs etc.

    I'd really like to be able to buy the whole package from NVIDIA one day with official support. Missing a potential market.

    Just ordered a GTX-770 4 GB card. When i receive the card i will test the eGPU setup again.

    If requested i can post detailed instructions how to edit Nvidia driver and KEXT's. It is the same procedure for OS X Mountain Lion, Mavericks and Yosemite (except in Yosemite you have to disable KEXT signing).

    So you can output the 570 to the internal screen as well as a monitor?

    I think this is an amazing idea and would love to also do this but I would want a tiny compact egpu that I could move with me, the itx case idea works great but you may as well just build an itx rig!

    Aprox 300$ without the card.

    I think its not worth it. You can buy a Fx6300+4gb+cheapboard+case for that price and have entirely computer

    GVA, KUL, MEL (current), ZQN
    Minus the Mac hardware and a properly functioning OS X experience.

    Hackintosh isn't the same.

    I've got a Sonnet IIID with a GTX 780 Ti, hooked up via TB2 to my Mac and it's smooth in Boot Camp. Just plug and play.
