1) As flexxar said, if you are getting a dedicated card, there is no reason for an APU. The CPU portion of the APU really isn't that powerful, but with a really good integrated graphics chip it makes it a nice all in one package. Swap it out and get an AMD FX-6300 and supporting motherboard.
2) Drop the alpine power supply and get a more reputable brand. You also don't need 700Ws, you can get away with 500-550W easily for something like you are doing.
3) Why would you get a last generation GPU? Skip the 560TI and get a GTX660 or higher. Also, don't mess with water cooling a lower end GPU. The blocks are expensive, factory installed or not. You are better off getting a higher model GPU for the money.
4) Budget? Site you are purchasing from? Where are the rest of your parts, motherboard, etc?
