Wow Don, you really took one for the team this time. Kudos to you, and the lessons of this unfortunately dismal build. I understand and appreciate your duplication of parts used before (e.g. the GPU) for comparison purposes.
Ok then...
A few months ago, and again now, the 120mm Xigmatek Gaia is only $20 on Newegg; no promo code required. It was back at $35 in the middle though, so maybe it wasn't cheap when you ordered.
I don't care at all for OCZ Sandfarce drives; they just aren't a risk I'm willing to take.
After reading the thread at
http://forums.hardwaresecrets.com/not-so-tough/8805 and the other links to which it led, I would not touch a Corsair V2 Builder. Surely $70 would have bought something better.
With Rosewill cases coming with extra fans, and looking pretty good too, the HEC didn't seem like a good choice either, but at least it wasn't a monstrosity like the "toy" one SBM featured.
If I win this one, I will put the CPU on my Sabertooth under a Gaia just to see if this was a bad chip, or you got a bad OC for some other reason. A decent OC could have really changed the perception of this build's performance (though its power use certainly did suck {pun intended}).
This build, like some of the past ones, argues for a single "do-over" per build, in which one unexpectedly poorly performing part is replaced for another. Whether cooler or mobo, the OC on this one was unexplicably poor.
