The Carbide Series 300R is a compact expression of the Corsair philosophy: great systems begin with a great case. Open the easy-access side panel to find a builder-friendly design with three tool-free optical drive bays and four tool-free hard drive bays with integrated 2.5 SSD compatibility. Theres room for extra-long graphics cards, and the matte black interior really shows off your gear. Finish off your build with a cable routing system that keeps wires and cables out of sight and out of the airflow path for a clean, uncluttered look.The 300R keeps your hardware cool with amazing airflow, including a 140mm front intake fan and a 120mm rear exhaust fan. Theres room to add five additional fans, including dual side-panel fan locations that can deliver cool air directly to your graphics cards. And, the dust filters are removable for easy maintenance. Features like these make the Corsair Carbide Series 300R the foundation of your next great system.
