Wow, I mean, the way you built it would be awesome, but I would spend that money alot differently.
You really should consider 2600k over the 1100T. With a good water setup, you may hit 5+ GHz easily and at low voltage while staying cool. They are faster and better all around. But, it does come at a price! You can scale back your system board and still have everything you need and plenty of oc headroom with quality VRM/Power. UD4, UD5, Asus Pro... ect.
Add a SSD as a boot drive. Big Big change. C300 (fairly budget friendly) on SATA 6.0 will get you 375MB/s read speeds versus 100 or so on a spinning drive. That is the one thing I would not ignore and could not do without when spending this much money.
Love the case. Stick with it.
Don't need a 1200 watt PSU. I love my 750 AX but, this is where you could shave a lot of cost that can be re-distributed towards other stuff.
The video card.... This may be the biggest blunder of your system or it could be the monitor choice. I am torn on spending so much. Latest greatest just seems like such a price vs performance rip off. Single card is better than SLI/Crossfire in terms of driver support and it working optimally. Pick the best one for under $400? $300? Let me expand on this. Your monitor is going to refresh at 60 Hz, so FPS above that is a non-factor unless you are going to pair this card with a monitor at 120Hz, it makes no sense.
Memory: 16gb is overkill. But, if you switch to 2600k, you can put DDR3 2200 in it! Ponder that thought intensly! 8gb is plenty. Heck even 4gb is plenty.
Nice keyboard, joystick, and pedals. How far are you going to sit away from the monitor?
I cannot help you with the water setup.
