Setting up, and installing a water cooling system may seem daunting. If you plan correctly, TAKE YOUR TIME, and leak test the system for a good amount of time before firing it up in a live system, you’ll be OK. When you get your H2O system, first you want to set it up and run a leak test for 24 hours, MINIMUM (you’ll be bangin’ your head against the floor to find out a .20¢ hose clamp just fried your $2000 rig). What you want to do is find an open space, non carpeted (I found the garage, or someplace with a concrete floor works well in the event of a leak) and lay down some old newspaper (the newspaper will make it easier to find any leaks). Arrange your setup in a circle (Pump/Res, Block, Rad), with a big bowl in the middle, and connect the components up.
