This is a solid guide. Have been enjoying this little beast of a board for more than 6 months now. Just put in 2x980Ti Hybrids with radiators sitting on the roof of the Phanteks Evolv mATX case. Things are running smooth. I am wondering though if there is a way to put back in the OSXWifi card somehow? The second GPU is covering the 1x slot. I tried a PCIe extension cord and it's a no go. Mobo has an error code of 99 and doesn't boot (Yes I thought I put it in wrong, but it was put in correctly). When I take out the extension it boots fine. I even built a little box to put the OSXWifi inside the walls of the case with taped WiFi/BT antennas in the case. I kind of gave up and using Ethernet for now. Continuity would be nice though. EDIT: BTW is it worth using 17,1 instead of 14,2? I'd like to keep using 14,2 so I don't have to deal with the black screen fix after every update. If 17,1 will give more speed to the CPU, will definitely switch though.
