High-end PC case for optimal customization
The ROG GR20 Edition 20 case embodies ASUS excellence in design and performance. Designed in aluminum with an open-frame structure, it combines refined aesthetics, robustness and flexibility for PC enthusiasts. Ideal for advanced builds, it supports EATX motherboards, graphics cards up to 368 mm and radiators of 360 mm, while providing optimal airflow.
Modular design and innovative cooling
The ROG GR20 stands out for its versatility with three placement options: vertical, angled or horizontal, adapting to all spaces and needs. Its integrated cross-flow fan provides broad airflow coverage, optimizing the cooling of key components, including SSDs.
