Add in the Swiftech H240-X for $150 and I broke ya budget by $13.70 but that includes shipping
The why's....
-MoBo / CPUU - X99 makes sense with 3 GFX cards or more. The MoBo here has a water cooling block which ya can add to the Swiftech H240-X loop
-The H100i comes close to hitting 70 dbA, my vacuum cleaner is quieter than that. The Swiftech H220-X kicks its tail thermally while being 1/6 as loud and the H240-X is quieter and cools better. You can also "open the loop" and connect it to the Motherboard water block.

-2133 CAS 9 is about as fast as 2400 CAS 10 and right now significantly cheaper.....Plus they're Mushkins w/ Hynix modules which means ya have good shot at overclocking them to 2400 tho I wouldn't bother.

-Ya had an SSD but that don't help your games load any faster when they sitting on the HD. SSHD changes all that.
-The 970 is just about as fast as the 780 Ti but with lower power and costs, now ya have two of them.

-Attractive, better reviewed and more features in the Phanteks case.... built in fan control, built in RGB LED color changing system with controller, set up for water cooling.
-Power Supply - 10 year warranty, great price, great performance and great build quality.
-Ya had the budget so went all out and got you the best gaming monitor that has ever been made.
