How will this far in gaming? I am looking at building my own computer that will last for a long time. Are these all compatible? For liquid cooling, how does that work? do you get the liquid cooling system with the case or is separately? Is there any real need for liquid cooling?

For gaming, you would see little to no benefit from the more expensive 3930, and higher priced motherboard. Another problem is using a cheap power supply and cooling fan for all those expensive parts.
As far as water cooling goes, for me anyway it makes my skin crawl. On little mistake, or leak and all those parts are dead. Air can't short out your computer. Using the 4670k you will have more than enough power for any gaming. It will run cooler, and the savings allow you to bump your video card to a Titan, which is the most important part of a gaming build.
PSU's too weak! At least get 650W XFX PSU for current and 850W/1050W PSU for future usage. Remember u should buy modular PSU to ensure stability and sustain more heat. XFX, Seasonic and Corsair are good brands.
