CM 690 III is a revolutionary update to the popular CM 690 II mid-towers. The exterior retains the curved metal mesh look the series is known for. The interior has been completely updated – the HDD/SSD combo cage can be switched between 3.5-inch or 2.5-inch drives by adjustable trays without any screw. There's enough room for a 240mm liquid cooling radiator at the top or front, 120mm in the rear and supports up to 9 fans, including 3 large 200mm fans for extreme airflow. And cleaning is hassle free thanks to the multiple dust filters at the bottom, top, and front.
