It's actually absolutely unbalanced IMO... For how it's built, you're going to be editing/encoding videos and doing CAD renderings like a madman with that thing, while gaming remains an extra...
Drop X99 and go for a more common Z97 paired up with an i5/i7 4690k/4790k. Drop DDR4 and go for DDR3 @1866mhz or higher (make sure the voltage is 1.5v up to 1866, and 1.65v above it). The advantage provided by both in gaming and compared to their lower counterparts is truly minimal.
Drop the liquid cooler unless you're going to do some insane overclocking and get a Noctua air-based heatsink.
Sink the extra money you'll save into a SLI/Crossfire system (two way, possibly, or three way if you're prepared to experience a couple issues every now and then, either with GTX 970s or 290xs). Drop the case to something less pricey (sheesh, 200$+ for a case? Plenty of towers/mid-towers with plenty of space and half the price), and get a 120hz monitor if you want 120fps. The rest looks OK.
You'll pretty much have a DEFINETLY better gaming experience for the same cost, if not for less...
Happy dreaming ;-)
