Right then, here we have the CM 690 II Advanced. The advanced model comes with the top HDD bay which we'll show you in a minute. If you purchase the regular version, you will forfeit on that feature. The packaging is done carefully, the chassis is packaged in a plastic bag and sits safely in Styrofoam, very safe for transportation.

Here we have the chassis unpacked. The CM 690 II Advanced. A mid-tower chassis with a plethora of options and features. The overall design is kept simple and slick. All the way through A to Z a black coating, even on the inside. At the frontside the bezel is a combination of metal and plastic, pleasing to the eyes alright. The bay covers are meshed for better ventilation, featuring air filters. In fact all meshes have dust/airfilters. All the way below we can find a 140-mm fan on the front panel (1,200 rpm, 19 dBA, which emits a blue light when turned on with an on/off switch for the LED’s. It is the primary air intake and blows external air directly over the HDDs.

Here you can see the left side panel. Two gaps here for installation of fans, you can mount accommodate 80, 92, 120 or 140mm fans. No side see-though window, though the honey comb mesh will allow you to have a peek inside.

When we flip around the chassis then on the right side panel we again see an opening, though smaller and it will fit a single 80mm case fan.  It's an interesting idea to have some sort of airflow flowing in or over the backside of the motherboard tray, remember that there's a gap in the motherboard allowing not only easy access, but thus airflow with the help of a fan on the backside of the motherboard as well.
