Overall i'm very happy with the stellar performance of this system. 

Thanks, i'm going to swap the side fan around so it pushes air into the cards.
From what I've seen so far this thing absolutely tears through milkyway@home spitting out three 213.76 point wu's every 59-61 seconds without fail.
 
The sapphire card won't crunch at 960MHz though it jumps right down to 925 for some reason, but for games and benchmarks it runs correctly.
