Do not go with Alpine power supply. It sounds like some junk PSU brand. Go with something like an Antec or Seasonic or even Corsair.
Do you really want liquid cooling? A good aftermarket cooler like the Hyper 212+ would be just as good, unless you plan on doing strong overclocks.
Are you sure you want 560TI's in SLI? A bigger single GPU would be much better (IMO).
Other than that, looks good. Maybe even change the processor - Do you really need Hyper threading with the I7 2600K? The 2500k would be cheaper and is just as good for gaming.
