Another closeup of the video card area. The tube coming in from the right comes from the pump and splits. The black tube exiting the top goes to the CPU block. The 6mm hose goes to the Northbridge MCW30 block visible (out of focus) above the video card. Then the black tube coming down from the top in the right of the picture goes to a quick disconnect and then to the hard drives in the lower bay. (The quick disconnect is necessary, otherwise you wouldn't be able to take the hard drives out.) Then the tube comes back up from the HD block to another quick disconnect and a drain plug and then exits the picture to the left, going to the radiator.
