WC kit generally looks fine. However I would note the following...
- The rad you have chosen is a single thick rad. Whilst this will be ok, I would personally want a double thick rad.
- Check that the EVGA card has a a reference design PCB to ensure fitment of the waterblock.
- I would be more inclined to use compression fittings as opposed to barbs (this may require a different CPU block and 1/2" ID 3/4" OD hose).
- That res isn't exactly a looker. If you could find something that will house the pump in the back of the bay res, then that would be a definite win.
- You will be needing coolant
Everything else looks fine off the top of my head.
