The Obsidian Series 650D mid-tower case is manufactured with strong, stamped steel parts for increased rigidity, and coated in a black textured paint. The front panel features a black brushed aluminum faceplate to bring a subtle elegance to your next build. A large 200mm front intake fan placed behind the front dust filter quietly pushes vast amounts of air over hard drives and video cards. The air is then exhausted by a second 200mm fan on top of the case, as well as a 120mm fan at the rear. The top fan can be replaced by dual 120mm or 140mm fans, and is pre-spaced for a dual radiator if you’re interested in water cooling. All fans are controlled by a three-mode, four-channel fan controller to help you make your own choice between noise and performance.
