Optiarc 24x DVD+/-RW
OCZ Fatal1ty 750W
Cooler Master HAF 932 AMD Edition

The Cooler Master HAF 932 is on Swiftech's list of certified cases for the 320 Edge, so I was not expecting any problems installing it. I will say however that getting the MCR320 into place does require angling the unit and twisting it in order to get it to clear the side of the 5" drive bays. For this reason I ended up not installing it with the pump towards the rear of the case as shown in the 3D model and first picture above, since this would not leave enough slack in the tubing to allow removal later for checking or topping off the fluid level. I also removed all of the fans temporarily as they were installed on top with airflow blowing down, and I wanted them to blow up from the bottom. I opted to leave the Cooler Master 200mm fan in its original location in the top panel and mounted the MCR320 below it. I also had to relocate my optical drive from the top bay to the bottom one.

The Apogee XTL block AMD mounting kit does require some assembly and is not quite as simple to install as the Intel bracket, nor quite as clean looking once completed. Due to the screw and spring design there is also a danger of overtightening and bending the mounting plate, and the instructions specifically state to be careful and stop turning once the springs are compressed to the height of the plastic spacers. After the radiator is reinstalled with the pump facing towards the front and the tubing cut to length, all that remains is attaching it to the 1/2" barbs at either end using the provided plastic clamps, making sure that the outlet of the MCR goes to the center inlet of the XTL block.

Although the HAF 932 includes a fill port hole at the top front of the case, it is designed to line up with their own branded Aquagate reservoirs, and is nowhere near where it needs to be to reach the MCR320. Some users may opt to drill a new hole in the top panel or make a filler tube with some 90 bends, however it is easier for me to simply pull the MCR out of the case temporarily. Once the HydrX coolant is added and then topped off with distilled water, the system should be primed and leak tested prior to actually powering up the computer. This is easily accomplished by disconnecting the main 24pin ATX connector from the motherboard and attaching it to a PSU tester as shown, or by jumping the green and black wires together.

The MCR may need to be tilted with the reservoir end up and drive end down in order to make sure there's enough liquid in the pump to prime it. When the system is first powered on there will be some capitation and foaming of the coolant by the impeller, causing the liquid to appear cloudy as shown in the first picture above. This is normal and should subside after a few minutes, after which you will want to power down and top off the reservoir with a final amount of distilled water so that the system is completely full. Then the MCR can be reinstalled into the case and powered back on. Swiftech recommends running the unit for up to three hours to ensure there are no leaks before reconnecting power to the computer. Rather than reinstall the supplied fans I opted to replace them with some red LED units from Coolmax to match the rest of the lighting in my case. There is a negligible difference in specs, 81cfm for the supplied RS fans vs. 85cfm for the Coolmax, so performance should not be affected.

With the H20-320 Edge installation complete and leak free, we're ready for some testing!
