If you're going this all out, get an EK AIO cooler, either directly from EK Waterblocks or from Amazon. It'll need to be bigger than a 120mm for such a beast of a CPU too, luckily that Antec Torque case will support a 360mm AIO. Alternatives to that would be the Lian Li Galahad, the Arctic Liquid Freezer II, and the NZXT Kraken. Those are the four best performing AIOs on the market right now.
Also, I don't see any 4x8GB RAM kits on Thermaltake's site, if you're planning to buy 2 16GB kits and put them together, not a great idea. They might not run at that rated speed, and you won't have the luxury of just enabling XMP/DOCP for automatic RAM tuning, you'd have to tune an unmatched set of RAM sticks manually, which is not fun. IMO you should look up G.Skill's offerings, find out which of their kits that supports the Dark Hero is in your price range. If you want RGB, their Trident Z Neo line is what you will want to check out. The lower the numbers in the timings, the better the RAM is.
EDIT: also, everything
