Nice clean build BP! I always drool looking at the Switch 810
[Spoiler alert Brandon]
I've had that board and surely enough, it was the worst GB 1366 board I've worked with when it comes to OCing. As evident with your screenies, it takes a considerable amount of juice to get to 4 Ghz. My older (and venerable UD5 can get to 4.0 stable with <1.3v). I was working with a 920 back then so you might have a better luck with a 930 once you start tweaking your settings. You can't really complain when it is free right

?
Oh and the pushpins have to go, save yourself the headache this early
Edit: the more I look at that Switch 810 the more I want it
