SPCR has a great review visual walkthrough here:

It does well aircooled, and even did well with a passively cooled heatpipe on a Preshott (

Looking at the case got my mind going for a WC project.
1. Isolate the rear portion of the PSU chamber so that the PSU is separate from the front lower case. It will only have to cool itself, which should keep the fan quiet.
2. Rip out the lower chamber fan and put a twin 120 radiator (BIP2 or HE120.2 or heatercore, with fans) there lengthwise (sitting vertically on one of its long sides) and duct airflow from the front opening, thru the rad, and out blow holes in the case side cover.
3. The pump could either sit in front of the PCI slots, assuming they are empty, or where the removable HDD bay is. (I put my HDD in a 5.5" enclosure anyway. A swiftech pump/bayres would work great too.
4. Use the top or rear 120mm fan for mobo and hdd airflow. Seal off the other one.
All the main heatsources are isolated from one another, and the fans are kept far from the front case openings where they would be easily heard. The PSU and rad in particular get fresh air without dumping heat to one another.
Any thoughts?
