Water Cooling - Do I have the right stuff?

Well damn. You certainly have been thorough. In any case you CAN use all that stuff but you also could accomplish your water cooling using a pre-made kit which are not necessarily as good as custom ones like yours. However, the same visa versa can be said of custom sets so really it all comes down to know how of the person setting it up.

If you follow this link below they have some good and water cooling to start with if you want a simpler set up:

Oh, and as an aside, if it leaks which can and will happen according to Murphy's Law your system is screwed so I recommend using mineral oils to replace the water. These work just as well but it does not fry your system in case of a leak.

+1 on your research. Good job picking your parts. Now you need some clamps and fans, as well.

+1 on DO NOT USE MINERAL OIL. Check, doublecheck, and recheck your conections and you don't need to worry about leaks. With the 7/16" hose, as I am sure you probably already know, it will fit tight to the 1/2" barbs, and for the most part, you won't have to worry about using clamps, although I would do so anyway.

I would recommend that you take it easy on overclocking both the vid card and cpu in the same loop. That can be quite a load on the radiator, and keeping it cool could take some serious fans. This means more noise.

You may consider a second loop for the video, if you find the heat or noise is too much.

Good luck on your build. Let us know how it goes!!!
