Pictures to follow. This will be an interesting build. Picked up a z820 with the later boot block date for $300, just waiting on that to arrive at the moment and then I can get started. CPU is very cool, and quite rare. It's a Xeon E5-1680v2 and it has an unlocked multiplier. There are obviously no overclocking features in the bios on a z820, but I should be able to use throttle stop to overclock it (via software from windows). This thread will serve as a build log and will update as soon as the Z820 arrives. Single CPU only, unfortunately. Only one QPI link.
