Took me about 4-5 hours to finish, the biggest problem I had was with the CPU cooler, I didnt get how to make it fit then I realized the screw is moveable you can move it a bit farther so all the holes align with the mount points I did a lot of cable management in the case, The case comes with two fans which was nice and the easy drive bays helped a lot.
Update 3/28/14 Added photos
Update 3/30/14 Added screenshot with 4.2 Ghz stable.
Got it to over clock stable while keeping temps under 60 degrees Celcius took me about 4-5 hours to get it right running Prime95, and monitoring with CPU-Z and SpeedFan. I tried several different methods I found, a youtube video helped me the most and that kinda help me with a baseline. https://www.youtube.com/watch?v=T9uXysmgPi8 I tried his setup but right away with Prime95 it crashed so I took the multiplier down to 20 then worked in increments and I also lowered the voltage from what he had to keep my temps down. I ran Prime95 for about 2 hours while adjusting settings and it never errored out and the PC didnt crash. I added a screen shoot to my final settings
Update 4/4/14 Was able to overclock more stable multiplier at 21.5 @4.3Ghz Vcore is at 1.27v-1.29v at least thats what CPU-z is reading in the actual Asus Motherboard tool it says 1.325, my cpu temp is lower around 55 at full load with Prime95
