A good mid-tower like a Phanteks Enthoo M, Fractal Design R5 or Thermaltake F31 should easily house this equipment.
Personally I find liquid cooling a waste of money in this build. Unless you're going for it because of aesthetics, it serves little purpose as the 6700k can easily be cooled by a 35$ cooler
Unless you're ordering the GPU directly from EVGA don't get a FTW ACX. They got a cooling issue where they forgot a thermal pad. Go with something else instead, like a Zotac AMP, Gainward Phoenix, Asus Strix or MSI Gaming X. Scrap base clocks, all these cards boost to ~2000MHz no matter what they're advertised as.
For the PSU a decent 550W PSU will easily suffice. Take a look around and pick what you get cheapest:
Super Flower Leadex / Golden King
Evga supernova G2 / GS
Corsair RMx / RMi
XFX XTR
If you're already on a budget or don't need modular cabling:
XFX TS Gold
Seasonic G
If those are all still too expensive, Seasonic S12II, XFX Pro / Core or Corsair CXM550 will eventually be alright.
As for your build, J wouldn't spend so much money on a 256GB SSD.
Yes this SSD will most.likely be faster than a SSD that costs half. But does it matter if you scrap 2 more seconds off booting time? You can get a very fast ssd of that size at half the price, heck you can get a decent SSD of that size for 70$
That cash is better saved / reinvested imho.
