No mate fortunately mine does not. When it comes to coil whine it's a lottery really. Any brand/model can get it. My Corsair TX750 didn't, the CM Silent Pro Gold didn't, my little brother's Corsair HX750 has it a lot, and my current Corsair AX850 does not have it. Very random indeed.
Great build! I love the colour scheme and to my tastes you did it with just enough colour, the only thing I can say its a shame the Zotac GTX680 AMP! Edition wasn't out when you were building it.
Looks amazing. I love all the white and orange. That cpu cooler is so good looking! How have you found your NZXT LED kit? I found that mine flickers and a few other people have reported the same thing? One guy said he had 4 in a row that flickered.
