Jonsbo has launched the BO400 VP aluminum PC case on JD.com, priced at ¥1 999. The chassis features a vacuum plating process and supports 360mm liquid cooling systems. It offers ten fan mounting positions and utilizes an ATX dual-chamber structure with dimensions of 474mm x 311mm x 489mm, weighing 12.9kg.
The internal frame is constructed from twelve aluminum profiles and eight die-cast corner pieces connected via mortise and tenon joints. The hollow frame is 2mm thick, while the front panel uses 6mm CNC-machined aluminum with an anodized brushed finish and nickel-chrome electroplating. The front panel indicator light is compatible with ARGB control systems.
The case allows for interchangeable side panels, enabling users to replace the default metal top cover with an included glass panel. It supports vertical GPU mounting via the A50 PCIE5.0 bracket. The front I/O panel includes a power button, reset button, audio port, two USB-A 3.2 Gen 1 ports, and one USB-C 3.2 Gen 2 port.
