Hello reaper. I managed to fit a msi 970 gaming in mine. I had to do some modding to allow the coils to fit since the twin frozer is a little wide for the frame. I took the side panel off so it's open on that side. I added two laptop blower exhaust fans to pull the hot air out. I have one blower next to the card on the outside next to the x51 and one inside where the DVD drive was to pull air up and out the other side of the pc. I seem to regulate heat pretty good even with extreme overclocking. I've managed to get hold about 60 degrees even with clock of 1650 mhz gpu.
