Mid-tower ATX chassis with back-connect support

The JONSBO X400 GRAY is a mid-tower case built for ATX, Micro-ATX and ITX motherboards including back-connect designs. A 3D skeletal frame and double-glazed tempered glass panels create a sea-view showcase for component lighting. It targets builders who want a clean internal layout and room for high-end air or liquid cooling.

Steel and glass construction with thirteen fan

The chassis uses ABS, SPCC steel and tempered glass. Thirteen optional fan positions cover top, bottom, side, rear and back zones, while radiator support reaches 360 mm on the side and 240, 280 or 360 mm top and bottom. Front I/O provides two USB 3.2 Gen 1 Type-A ports, one USB 3.2 Gen 2 Type-C port and a TRRS jack. Dust filters are fitted throughout.

Upgrades from tighter mid-towers

Builders moving from cases limited to shorter graphics cards or narrower CPU cooler clearance gain 427 mm GPU length, 176 mm cooler height and 180 mm PSU depth. The back-connect motherboard tray removes cable clutter from the main chamber, and vertical GPU mounting is possible with a separate bracket and riser cable. The jump is worth it when a 360 mm side radiator and full-length card must coexist.
