I would be very suprised if it did not. The Ninja raises a good deal before the fins start taking up real estate. The only issue I had with it was that my case was not really wide enough. I now have scratches all over the inside of my Plexi side because of the fan clips...2 more mm and I could not have used it.
Upon further inspection the socket looks really close to the top of the board. Depending on your case, you may have to try and find a way to slide the board down away from the psu, otherwise I could see interference issues.
The ninja is a BEAST. But it is well worth any jury-rigging needed to get it in.
Check the ninja site for dimensions, then check the Abit site for dimensions and compare to make sure it'll jive.
