Depending upon which model of the Zalman LQ1000 you are looking at (yes, I was surprised to see varying versions with the same model name) the cooling system will look a little bit different. In the original model, heat pipes lined all interior panels of the case for a very stealthy way of radiating the hot liquid coming from the water block. An external rear mounted radiator was also used for additional cooling. In the updated model, a large but thin radiator with a mounted 220mm fan serves as the cooling method of the system. Included in the radiator unit is also the system's reservoir.
The unit's pump, rated for 300 liters per hour, is mounted on a vibration and noise-suppressant pad at the bottom of the chassis. While it seems like a strange place to put anything, it manages to stay out of the way of vital components and quietly does its job. The exception to this is in the instance where someone is using the 6th and 7th expansion slots with long cards, such as in a tri-SLI or crossfire configuration. If the cards are too long, like most high end graphics cards are, the one in the bottom slot will not be able to play nicely with the pump.
The real beauty of this case, though, isn't just in the streamlined and efficient use of space for liquid cooling, but also in the built in monitoring and control offered. The front panel houses several gauges, meters, and buttons used to maintain absolute control over your liquid cooling system.
