What do you think of this PC build, any ideas to make it better?

[Hectic Fowl]

Hello
So I am building my first high-end/full tower PC and I was curious what can be improved in my draft here. GPU's unfortunately are not something I can change since these bad boys are currently going for 220euro a pop as limited offer here (Bulgaria). Everything else though is up for discussion.

I would be more than happy if you share your opinions with me.

PSU: Seasonic 1250w X-series
CPU: i7 4790K
GPU1: Sapphire R9 290 Tri-X 4Gb OC
GPU2: Sapphire R9 290 Tri-x 4Gb OC
Mobo: AsRock Fatal1ty Z87 Killer (it is cheap compared to everything else, but do I really need anything extra?)
RAM: Corsair Vengeance 1600hz 2x4Gb Red
HDD: Seagate Barracuda 2Tb 7200
SSD: Intel 530 120gb
Liquid cooler: Kühler H2O 1250
Case: Cooler Master HAF X

This build would be better at a bit over 750 euros:
