Description

The ASUS ROG GR20 Edition 20 stands as a landmark in PC chassis design, blending industrial-grade 4mm aluminum construction with the high-performance requirements of modern enthusiast hardware. By utilizing an open-frame architecture, this case eliminates the thermal bottlenecks found in traditional enclosed towers, ensuring that high-TDP components receive direct, unobstructed airflow for sustained peak performance.

- Enthusiasts building high-end workstations with E-ATX motherboards.

- Gamers utilizing heavy-duty RTX 50-series graphics cards requiring reinforced support.

- PC builders prioritizing maximum thermal efficiency and open-air cooling dynamics.

- Modders and collectors seeking a limited-edition aesthetic with unique commemorative branding.

- Users who require flexible orientation options, including vertical, tilted, or flat configurations.

- Dimensions: 285 x 513 x 470 mm

- Material: 4mm Aluminum frame with high-strength steel components

- Motherboard Compatibility: E-ATX (12"x10.9"), ATX, Micro-ATX, Mini-ITX

- GPU Clearance: Up to 368mm (Vertical or Horizontal mounting)

- Cooling: Supports up to 360mm radiator; includes 2500 RPM Crossflow fan

- I/O: 2 x USB 3.2 Gen2x2 Type-C, 2 x USB 3.2 Gen1, 1 x Audio jack

Building in the GR20 is a tactile experience defined by its modularity. The inclusion of a high-performance Crossflow fan is a standout feature, as it provides a wide cooling path that effectively lowers temperatures for both the GPU and M.2 SSDs simultaneously. The 36mm of dedicated cable management space behind the motherboard tray ensures that even complex builds remain clean, while the reinforced GPU bracket provides peace of mind for heavy, modern graphics cards.

Compared to standard mid-tower cases, the GR20 offers superior thermal headroom and a smaller footprint relative to its component capacity. While traditional cases rely on intake/exhaust pressure, the GR20’s open-frame design allows for immediate heat dissipation, making it a more effective solution for overclocked systems compared to glass-paneled alternatives that often trap heat.

- Does the GR20 support E-ATX motherboards? Yes, it is fully compatible with E-ATX motherboards up to 12" x 10.9".

- Can I mount my GPU vertically? Yes, the case supports both vertical and horizontal GPU installation with a reinforced bracket.

- What is the maximum radiator size supported? The chassis supports liquid cooling radiators up to 360mm.

- Does the case include cooling fans? It comes with a specialized 2500 RPM Crossflow fan designed to cool both the GPU and storage drives.

- How many orientation modes are available? The modular design allows for three distinct setups: vertical, tilted, or flat.
