Well I finally had all my parts in and started the build. As with most used HW builds the wildcard is always the motherboard. As you can see in my initial post I went with the ASUS Z8PE-D12 which had pretty good reviews and is feature rich. It even came with the iKVM board!
I knew it was going to be a crapshoot when I pulled the motherboard from its shipping box and noticed the middle of the motherboard had a very very slight bow in it running from north to south. I installed the RAM and 2 x Xeon x5690's and it posted right away. I did notice a slight and I mean very slight whine coming from the motherboard. Temps in the BIOS look decent so I booted into unRAID which was a success.
Decided to get lm sensors up and running and on the surface it looks like I may have an overheating issue on my hands.

Ok so that does not look right..... I walked over and the NB was extremely hot to the touch and I immediately placed a 40MM fan ontop of it which dropped the temps from temp1 to 56C. Temp2 is still way too hot I think I will need to find a mobo replacement
