Details

The Jonsbo X400 Gray is a bold, mecha-inspired ATX mid-tower chassis that combines striking 3D skeletal frame aesthetics with serious cooling performance. Built around Jonsbo’s signature exoskeleton design language, the X400 delivers a rugged yet refined presence with its deep gray metallic texture coating and dual tempered glass panels for a panoramic “sea-view” display.

Designed with a dual-chamber internal layout, the X400 separates key hardware zones for improved thermal efficiency and cleaner cable management. The double-glazed glass panels showcase your components from multiple angles, making it ideal for RGB-focused gaming builds and high-end performance systems.

With support for up to 13 fan positions and multiple 360mm radiator placements, the X400 is engineered for powerful airflow and advanced liquid cooling configurations. A patented auxiliary air-cooling system directs airflow toward motherboard power components such as MOSFETs and VRMs, helping to maintain stability under high-load conditions.

Compatible with standard and back-connect ATX motherboards, the X400 creates a cleaner internal appearance by routing cables behind the motherboard tray. Combined with removable dual cable management panels and tool-free access panels, installation and maintenance are straightforward and builder-friendly.
