Modular Case System

The FRAME Modular Case System redefines customisation. You can upgrade the motherboard tray to billet aluminium. You can also replace the front I/O panel for more USB ports. This design ensures the chassis adapts to future hardware standards. It offers near-limitless options for upgrades and changes over time.

Infinirail Fan Mounting System

The steel Infinirail system provides unmatched fan flexibility. You can slide the rail to mount fans up to 200 mm in the front. The roof supports up to 140 mm fans. This removes the limitations of fixed mounting points. It ensures targeted airflow exactly where your components need it most.

High-Airflow Front Panel

The 3D Y-pattern steel front panel is engineered for minimal resistance. It creates a smooth, unobstructed path for cool air. This design improves overall cooling efficiency. The panel also includes an anti-dust filter to keep your interior clean. It is a key part of the case’s thermal performance.

Dual 360mm Radiator Support

The case supports extensive liquid cooling setups. You can mount 360mm radiators in the front, roof, and side. This allows for up to ten 120mm fans simultaneously. It ensures efficient heat dissipation for high-end CPUs and GPUs. The layout supports both air and liquid cooling configurations.

Clean Build Features

The chassis includes a GPU Anti-sag Stabilization Arm. This keeps your graphics card steady and protects the PCIe slot. A cable shroud hides unused or long cables. It is also compatible with reverse-connector motherboards from Asus, MSI, and Gigabyte. This allows for unobstructed airflow and a super-clean interior.

Modern Front I/O

The front panel provides easy access to modern ports. It includes one USB 3.2 Gen 2 Type-C port. You also get two USB 3.2 Gen 1 Type-A ports. A combo headphone/mic jack is included for audio. All ports are positioned for convenient reach.
