COOLER MASTER HAF XB Evo Mesh ATX Mid Tower Cabinet (Black)

The Cooler Master HAF XB Evo Mesh (model RC-902XB-KKN2) is an ATX mid-tower cabinet designed with both builders and overclockers in mind. Its standout feature is a removable motherboard tray that allows you to quickly reconfigure the chassis into an open test-bench layout — handy when you need easy access during extended tuning sessions or component swaps. The rigid carry handles integrated into the side panels make transporting the entire system straightforward without disassembly. Airflow is a priority throughout the design. The mesh front bezel and mesh top panel promote direct, unobstructed intake, while two pre-installed 120mm Cooler Master XtraFlo fans (rated at 1,200 RPM and 17 dBA each) provide quiet baseline airflow from day one. Builders wanting more cooling headroom can optionally add a single 200mm fan at the top, swap the front pair for 140mm fans, or fit a 120mm or dual 80mm fans at the rear. A front-mounted 240mm radiator slot (compatible with the Cooler Master Nepton 280L) and a rear 120mm radiator slot round out the liquid-cooling options for those pursuing a custom loop or AIO build. Storage flexibility is generous: four 3.5-inch drive bays sit in removable cages, and all four can be converted to 2.5-inch SSD mounts, giving up to four drives regardless of form factor. Two 5.25-inch external bays accommodate optical drives or fan controllers. The X-Dock bays on the front panel offer tool-free 3.5-inch or 2.5-inch hot-swappable drive access for quick plug-and-play storage management. The front I/O panel provides two USB 3.0 SuperSpeed ports alongside HD audio in and out jacks. Seven expansion slots accommodate multi-GPU or multi-card configurations, and the case accepts ATX, Micro-ATX, and Mini-ITX motherboards. CPU cooler clearance reaches 180mm, VGA card clearance extends to 334mm, and the PSU bay accepts standard ATX PS2 units up to 180mm in length. A slide-out dust filter simplifies maintenance.
