Up and running again. Thanks for all the suggestions.
What board did you go with?
I went with a new unbranded board...not without some reservations. It's worked flawlessly. I did have a problem initially with the cpu running at 1.2 ghz. Turned out that in addition to losing the psu which burnt the board, I also lost the H100i cooler. Basically everything went to hell and I rebuilt it starting with only cpu and memory. I replaced the H100i with a Hyper 212 and the 3930k @100% load @3.8ghz now has all cores at 40c or below.
I should have bought a hyper 212, those things are an amazing value.
