Quality Construction The Obsidian Series 650D mid-tower case is manufactured with strong, stamped steel parts for increased rigidity, & coated in a black textured paint. The front panel features a beautiful black brushed aluminum faceplate to bring a subtle elegance to your next build. Excellent Cooling A large, black 200mm intake fan hides behind the front dust filter, quietly pushing vast amounts of air over your hard drives & video cards. The air is then exhausted by a second 200mm fan on top of the case, & a rear 120mm fan. The top fan can be replaced by dual 120mm or 140mm fans, & 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 should you want to make your own choice between noise & performance.
