Cooler Master HAF XB ATX LAN Box PC Case
The Cooler Master HAF XB (RC-902XB-KKN1) is a High Air Flow ATX LAN box case supporting ATX and Micro ATX boards, GPUs up to 334mm, and 240mm radiators. Its removable mainboard tray and side panels with rigid carry handles allow instant conversion to an open test bench.Overview
The Cooler Master HAF XB brings the renowned High Air Flow philosophy to a compact, rugged LAN box form factor optimised for extreme cooling performance and dual-purpose use as a test bench. A removable horizontal mainboard tray and two front-mounted 120mm fans create a powerful front-to-back airflow path, while the robust chassis accommodates tower CPU coolers up to 180mm, graphics cards up to 334mm, and 240mm water cooling radiators with clearance for thick performance cores. Within seconds, the windowed top panel and side panels — each fitted with rigid carry handles — can be detached, converting the HAF XB into a fully open hardware test platform.
