Water Cooling Help

Hello all,

I have been doing some reading and have some questions based on my homework, I recently upgraded my entire pc, I have an Antech 1200 case, I am not happy with my temps currently with air cooling so I have started investigating liquid cooling.

This is my first time for water cooling, and I am trying to be prepared before the parts arrive, I also am finding it difficult to order all the parts connectors clamps etc, and secondarily visualize or draw out the flow of water through the system, which I believe has to be a dual loop configuration bc i have dual gpu's that draw 298 watts a piece lots of heat! here are my specs to start off.

OS

Mother Board

My mother board manual is here http://www.evga.com/support/manual [...] L-E758.pdf

So basically I have read up on the system components I think I need, I will be cooling the following components Dual GTX 295's in SLI they are in slots 1 and 2 of my mother board which are right on top of each other, this is because those two slots operate at 16x or 8GBS, the pci express slot at the bottom of the mother board is a x8 slot. I will also be cooling the north and south bridges and the cpu, I am most concerned with having my video cards being the coolest I use the dummy oc feature in the evga mobo but nothing more for cpu overclocking yet! :-)

I have looked up the following components and connectors, hoses etc for the system, can someone please take a look and tell me if I am on target missing anything, or any advice?

For my cable width I used http://www.primelineindustries.com/pdfs/sizechart.pdf

I believe I will be running 1/4 off the back of the cooling unit it will be 3/8 inside the case, then 1/4 inch to the water blocks then converted back to 3/8 although for the cooling unit I was a bit confused it says it has 1/4 entering and exiting but then it says it supports 3/8 inch

I have used the following guides to help me come to this point
