Product Information

Eclipse G400A
Spacious D-RGB Gaming Chassis
The G400A is the upgraded successor to the popular P400A, featuring a completely redesigned and more spacious chassis. It’s perfect for clean, modern hardware setups, easily accommodating even the largest graphics cards while leaving ample room for cable management. With up to 10 fan mounting points, support for 140 mm fans, and dedicated radiator space at the top, cooling performance has been significantly enhanced.

The G400A also supports the latest mainboards, with rear-side connectors hidden to enable a cable-free appearance. Additionally, the graphics card benefits from direct cooling via three 120 mm fan mounts on the mid-plate.

4x M25-140 Gen2 D-RGB fans included.

Dedicated 360 radiator support in the top without restrictions.

Triple mid-plate 120 fan locations for direct GPU cooling.

Support for the largest graphics cards without compromise.
