Oh wow, you have like my dream setup right there with those GPUs and PSU. I've had a Tri-X 290 for a while and I've been wanting to crossfire it and get that exact PSU (for the color scheme, black with yellow accents) soo bad. Either that or mod the Tri-X to red and black for an AMD-styled build. Anyway, when I get a working rig up again, a setup like yours is definately going to be my goal!
Pretty damn awesome system, well done!
That black & yellow color scheme is complete accident, and I got it like that this construction yard caution feeling.
So I ended up finishing it with those green Corsair SP fans, as I thought it'd look refreshing like that with all that yellow at it.
