ASUS ROG Hyperion GR701 Full-Tower Case - Semi-Open Cooling

In this review of the ASUS ROG Hyperion GR701 the bottom line is simple: builders who value expansive airflow, modular convenience, and a premium aluminum-exoskeleton will find a lot to like. The case's semi-open structure and support for up to two 420mm radiators deliver the single biggest reason to buy - exceptional cooling potential for high-end air or liquid-cooled systems. The review focuses on real-world assembly, internal space and the practical benefits of features like the hinged tool-free side panel, built-in graphics card holder and dual front Type-C ports.

Key Features

• Semi-open structure: The exoskeletal diecast aluminum-alloy frame improves airflow and gives the case a distinctive, ventilated profile that helps high TDP components run cooler.
• 420mm radiator support: Room for up to two 420mm radiators enables large AIOs or custom loops for extreme cooling headroom.
• Tool-free side panels: Hinged, tool-free panels simplify access for upgrades and maintenance, speeding up repeated builds or troubleshooting.
• Integrated graphics card holder: The built-in holder supports vertical and horizontal GPU mounting, preventing sag and showcasing large cards securely.
• Front connectivity: Two front panel Type-C ports with 60W fast charge support provide modern device charging and data convenience at the front of the case.
• ARGB and fan hub: An internal hub with 6 PWM fan headers and 8 ARGB headers plus Aura Sync compatibility centralizes cooling and lighting control for coordinated builds.

Who It's For

The GR701 is aimed at enthusiasts and custom builders who need a full-tower chassis with generous interior volume and top-tier cooling options; it is especially well suited to users planning multi-radiator AIOs or custom water loops, and those who value a premium metal frame and clean cable routing. The case also appeals to modders and showcase builders who will use the vertical GPU mounting and ARGB lighting.

Those with compact builds, SFF priorities, or who need a quiet, fully enclosed case for a living-room environment should look elsewhere; the semi-open design prioritizes airflow and style over absolute acoustic isolation.

Pros & Cons

Pros

• Excellent airflow and cooling capacity thanks to the semi-open frame and 2 x 420mm radiator support.
• Premium, sturdy diecast aluminum-alloy frame with top bars that can double as carry handles and support heavy loads.
• Convenient builder features including hinged tool-free side panels, a storage drawer and integrated graphics card holder for vertical or horizontal mounts.
• Modern front I/O with two Type-C ports and robust ARGB/fan hub for tidy builds and synced lighting.

Cons

• The semi-open design will not be as quiet as fully enclosed cases and may not suit noise-sensitive setups.
• Its large full-tower size requires significant desk or floor space and may be overkill for small builds.

Specifications

Our Verdict
