Wow wow and wow. The DQ77KB and E3-1220LV2 without a video card... one more WOW.
That's so exciting. Have you performed any watt readings, I'd so much like to know how this combination idles.
I was thinking of either about pairing with the E3-1265L v2 (45W with gpu). But if the E3-1220LV2 works and is powerfull enought (no idea how I calculate this) then this is wonderfull.
For any server ECC must be the prefered route, I did read this link http://communities.intel.com/thread/31007
which implied that because ECC is spec'd as not supported it doesn't mean it would not work! Interesting but until anyone can confirm this it is just chatter.
Any more observations on what you have built?
