The backview. As you can see, the trend nowadays for power supply mounts hasgradually shifted to the bottom of the case, which ensures that the heat within the case doesnt spur up the fan inside the PSU, thus generating more noise.
The Front I/O. as you can see, Coolermaster has gladly included a front eSATA port for easy access, something that is still quite uncommon less even in the higher end cases available in the market today.
The provision for water cooling tubing up to 1/2 inch is available at the back of the case.
