Open-Frame Aluminium Chassis

The ROG GR20 Edition is an open-frame E-ATX mid-tower built mainly from aluminium and steel. It targets enthusiasts who want unrestricted airflow and a showcase build that can sit vertically, angled or horizontally on the desk. The bundled crossflow fan pushes wide airflow across the motherboard tray and storage area. No power supply is included.

GPU And Radiator Clearance

Graphics cards up to 368 mm long are supported with the supplied reinforced bracket for stability. A side-mounted radiator up to 360 mm can be fitted using three 120 mm positions. The power supply bay accepts units up to 190 mm deep. Builders needing more than two vertical expansion slots or any 5.25 inch external bays will not be accommodated.

Detachable High-Speed I/O Panel

The removable front I/O module provides two USB 3.2 Gen 2x2 Type-C ports running at 20 Gbps and two USB 3.2 Gen 1 Type-A ports at 5 Gbps, plus a combined audio jack. This specific port mix decides whether the case matches a motherboard with matching internal headers and a user who needs front-access 20 Gbps Type-C connectivity.

商品問答

Will my current EATX board measuring 12 by 10.9 inches fit inside the GR20 Edition 20?

The case supports EATX motherboards up to 12 inches by 10.9 inches, so a board of that exact size will mount without issue.

How can I verify the bundled crossflow fan is actually moving air over my SSDs after I build?

Power the system and feel for steady airflow exiting the side of the frame; the crossflow design pushes a wide stream across the motherboard tray where M.2 slots sit.

Does the box include a power supply or do I need to buy one separately?

No power supply is included; you must supply an ATX unit no longer than 190 mm, which mounts at the bottom of the chassis.
