The Cooler Master HAF XB takes the famous high air flow series to a form factor with extreme cooling performance. The removable horizontal mainboard tray & large mesh top & front panels with two 120 mm front fans create a powerful front to back airflow. Despite its compact rugged design, there is plenty of space for even the tallest high performance tower heatsinks, thick water-cooling radiators & up to 3 of the longest high end graphics cards. Within seconds the side panels with their rigid carry handles & the top mesh panel can be removed, transforming the HAF XB into a test bench with direct access to the hardware. The front panel features two USB (Universal Serial Bus) 3.0 super speed ports as well as 2 SSD compatible X-dock slots for lightning fast data transfers.
