The JONSBO BO400 is an ATX Mid Tower case constructed with an SPCC steel frame and SGCC panels, complemented by tempered glass on the front and side for component visibility. Its 311 mm width provides a substantial internal volume for high-end hardware and cooling systems. The case supports ATX motherboards and is designed for builders seeking a chassis with extensive liquid cooling potential. Its internal layout is arranged to accommodate large components and multiple cooling configurations simultaneously.
Cooling capacity is a primary feature, with mounts for up to 360mm radiators on the top, side, and bottom panels. This design allows for complex custom loops or multiple all-in-one liquid coolers. The case provides clearance for CPU coolers up to 173 mm in height and standard ATX power supplies up to 200 mm in length. For storage, it includes dedicated mounts for up to four 3.5-inch drives and two 2.5-inch drives, supported by an HDD/SSD combo cage. Integrated cable management channels and removable dust filters aid in system assembly and maintenance.
