Three things I see with this system board:
1. Lift that silly blower off the NB and swap it for a water block - those tiny fans don't last 18 months running 24/7 unless they have very fancy bearings.
2. If I went with a pair of Mars 2 cards I would water-cool them. Problem is no water blocks exist for the Mars 2, and probably never will. A quartet of next-gen 600 cards running in quad-SLI will make this board scream.
3. Tom, you need to get your greedy little mits on a 8C/16T CPU...
Keep up the great work!
