Thanks. I think if it takes HPTX it should work, but I may have to make some standoff locations to support the board.
I also had an EVGA SR2 in it too and even that didnt fill it up, you should be fine with room, especially if you make some custom standoff locations. The case itself is pretty good too, everything has held up really well for the 5 years ive owned it, my power button broke (button fell off) but I just wired in the reset button for that and its good to go
I recommend getting a couple fan controllers if you decide to get it and fill it up with fans like I did.
