Cooler Master CM 690 II Advanced review - Product gallery - Exterior | Interior

Right it's time to look at the innards. After removing the side panel we again can't help it bit are are immediately impressed by the completely black coating, our eyes get lured instantaneously to the six 3.5" removable trays for your HDDs, we spot holes for cable / wiring management, which is nice. Quite different from the original CM 690 alright. There's also plenty of spec to work in, but not unimportant, large and spacious enough to fit bulky components in. The one card though would possibly not fit would be the uber--lengthy Radeon HD 5970 though.

To the rear side and top we see that there are two 120mm fans pre-installed. Both can be connected directly to the peripheral PSU connector, or to the motherboard/fan controller. They can be PWM regulated meaning you can adjust the fan RPM and thus performance. Let's zoom in a little at the top fan though.

Yep, there it is .. you can install a second one, or should you require to do so, you could also install a radiator for liquid cooling here. The mounts are already there.

The CM 690 II has space for six 3.5" HDDs. All the HDDs are installed on a removable and swappable tray. The tray can be secured tightly into the drive bay. To install the drive, you bend it outward on the side of the tray and align screw holes on the drive with the installation pins on the tray. Once you have the drive on the tray, simply slide it back into the cage and lock it into place. The installation pins are rubber coated, preventing vibrations and noise.

The top HDD tray has an included adapter inside it that will allow you to install two 2.5" or 1.8" drives on to it and can then be placed into the hard drive cage which is very handy for a SSD drive..
