1. The 4770k isn't helping you game, so save $100 and get a 4670k unless you will be running any program that benefits from hyperthreading
2. I can not recommend any "faux water cooling" device, the AIO / CLC units simply offer no benefit over the better air coolers at $75 such as the (in order of preference) Phanteks PH-TC14-PE, Thermalright Silver Arrow of Noctua DH-14).
many peeps recommend the H100 and "then get different fans".... here's what happens
Take listen of the H100 and decide if that's what you want to listen to before buying. many peeps say doesn't bother them as they play with headphones on so it's a "what works for you" thing.

3. The Hero is a pretty good motherboard but the same features and as good are better components and better performance are provided by the less expensive MSI Z87 GD-65 which has swept the board awards and performance crown wise in reviews. The Hero board is also plagued by a series of recent BIOS updates that seriously curtail overclocking stability but hopefully that will be resolved. If willing, take the $100 saved on the CPU and upgrade to the Maximus VI Formula which while an astounding board, is also currently plagued by the same BIOS issue.....hopefully will be resolved soon.
4. I don't see the 8 GB of 1600 when RAM is so cheap and faster speed is almost same price.
$79 for DDR3-2400

5. Good choice on SSD, HD I'd upgrade to Seagate's SSHD and yes, even with an SSD
6. I would stay away from any SC series GFX card from EVGA..... historically, all the SC series have used stock PCBs and VRMs while all the competition's factory OC'd (Asis DCII, Gigabyte Windforce, MSI N series)cards have custom PCB and beefed up VRM. iour VRM will run at much higher temps than GPU and having a beefier one means lower temps and better OCing.
7. Phantom is a bit small for twin GFX cards which you list in your upgrade plans..... Id want at least a 750D $130 after MIR and $10 off w/ promo code EMCPWHF49, ends 1/30) or Enthoo Primo ($230) both of which serve well for water cooling.
8. 650 watt PSU will not support your planned GFX card upgrade.

Here is Guru3D's power supply recommendation:
GeForce GTX 780 Ti - On your average system the card requires you to have a 550 Watt power supply unit.
GeForce GTX 780 Ti 2-way SLI - On your average system the cards require you to have a 800 Watt power supply unit as minimum.
My twin 780s draw 765 watts from the wall running Furmark and that is with GPU 100 watts shy of max load.
850 would be the bare minimum
$95 XFX Core 850

Corsair HX850 ($150) is only $12 more than your 650 watter and is one of the best 850s ever made. Seasonic X series is $170.
