Hi mshannon and welcome to the forums. Here is a pic of a very simple setup that may help you in understanding how it goes together.
inline watercooling. Now notice the "loop" it goes from pump to rad(Bi pro the little brother of the BIX), rad to block, block to T-line, T-line to pump. Now if your going to be using the vid and chipset block you would want to run the setup like this: pump-->T-line-->rad-->CPU block-->vid block-->chipset block-->pump. This senario would be assuming your using the T-line setup. Now here's a pic of a
submerged setup. The round black piece of the setup at the bottom is a resevoir with a pump inside "submerged" and you'll notice The "loop" I have a chipset block on that setup, but no vid block. I hope this helps you get a better understanding how it all goes together. I hope the project is a success for you.
