Front and top The front panel consists of start/reset buttons, power and hard drive LEDs, 2x USB 2.0 connections, microphone and sound jack connectors, an e-SATA connection and a button for enabling/disabling the blue LEDs in the front fans.
The front can be removed by using a handle. It's worth noticing the groves in the front. Cooler Master has placed their logo right in front of the 120mm fan.
One of the main features of the CM 690 II Advanced case is the hot-swapping, making it possible to install a hard drive at the top. You're free to install and remove the hard drive while the system is running, a feature some people might find handy. The hot-swapping feature supports 3.5" hard drives, and it isn't possible to hide the drive, as its simply too big.
