Use the Gigabyte ITX board instead of the Intel.
If only water cooling the CPU, may as well get an all-in-one kit like the Corsair H50 or the CoolIt Eco/Vantage. You will have limited space above the PSU for the rad so you may have to use a thinner 120mm fan than the usual 25mm. The CoolIt rad is very thin, which helps fitment. Either of these will fit better due to thinner tubing
If the 2TB Black will be used for both games and storage, I'd suggest a 1TB Samsung F3 for games and a 2TB Samsung F4 or 2TB WD Green for storage. Same cost, end up with 1TB more space and will be quieter. The Lian Li PC-Q08 case has plenty of drive bays.
The PSU is a bit overkill, plus might be a bit big. What I would do is to score something like an Antec Neo Eco 520W. The reason is that it is really short for an ATX PSU. Now, it isn't modular, but it is cheap so you should make your own cable harness. Might be as easy as cutting off the cables you don't need.
