Panoramic Showpiece Design

This case offers a seamless view of your components. Large glass panels wrap around the front and side. It creates a true showcase build. The design allows you to admire your hardware from multiple angles.

Invertible Layout & Footprint

You can change the case orientation in seconds. Relocatable feet let you flip the chassis or set it horizontally. This flexibility adapts to your desk setup or room layout. No tools are required for the transformation.

Advanced Cooling Capacity

The chassis supports up to ten fans total. It accommodates radiators up to 420mm in the top and bottom. A 360mm radiator fits in the side panel. This provides massive thermal headroom for overclocked CPUs and GPUs.

Neat Cable Management

A dual-chamber design hides drives and cables. This keeps the main chamber clear for airflow. The case supports backside connector motherboards (ASUS BTF, MSI Project Zero). It ensures a clutter-free interior view.

Integrated ARGB & PWM Control

The case includes two hubs offering 12 connectors. They are positioned at the top and bottom. This simplifies wiring for fans and lighting. You can sync effects via motherboard software or use the included button.
