Reason being is because it is said to be good for 24/7 loops with multiple components plus it has all the additives and looks unbelievable in tube resivoirs
I went with a Mayhem's Pastel Ice White. I really like their pastel line. They've got the most unique and vibrant coolants. Aurora is cool but from what I've read, it causes problems in the long term. It's just not worth the extra effort because you've got suspended glittery sparkles that will fall out if you leave it off for too long. It's meant to be a "show" coolant and not a 24/7 coolant. Besides, cooling performance of pastel colors is only about 1C worse than distilled water while aurora is a few degrees worse.
I personally like Seasonic power supplies. I've had a seasonic Platinum 1000W moved up to a Gold X-1250W for my 3 780's. Overclocked with the Sandy Bridge-E i can actually pull 1250W at the wall. My system shuts down from the power draw if I try to run furmark with Prime95 (unrealistic real world power draw). The Sandy Bridge-E can consume 400W of power fully overclocked and each 780 can eat up 265W. Under real world or 3dmark/unigine I pull anywhere around 800-1000W with 3 780's. With only 2 780's you would be doing 500-800W. Do the math, that's a lot of power. That said, an AX860i or a Seasonic 860W platinum is plenty enough for 2 780's.
With an all out system, you will want individually sleeved cables. If that's the case, I'd get a Corsair AX860i and buy a pack of their individually braided cable pack. It's the simplest way to replace the original cables. They come in all sorts of colors such as white green blue red etc.

Dual socket mobo's are only for work stations. You will need Xeon processors. The E series CPU's will not work on those mobos because they have their links disabled.
The best motherboard to buy with a 3930K or 4930K is an Asus Rampage IV Extreme. It's universally lauded for its performance and feature set. Only down side is it's expensive since it's the best of the best. Alternatively, you can go for a Asus Rampage IV Formula if you're interested in the high quality on board sound card. It's a great option if you aren't going to be installing a dedicated sound card. If you haven't figured it out, I'm a fan of Asus' ROG series.
