## Long description

ROG Strix Helios II is a premium EATX mid-tower gaming case with dual tempered glass side panels, an aluminum frame and front panel, and support for GPUs up to 450 mm in length. The chassis comes pre-installed with four 140 x 28 mm performance fans and offers extensive cooling options, including front support for up to a 420 mm radiator and a top mount for a 360 mm radiator. Designed for showcase builds, it supports motherboards from Mini-ITX to EATX and provides modular components such as removable fan/radiator brackets, a rear detachable PSU bracket, tool-free GPU clamp and hinged tempered glass for easy access.
Advantages
The Helios II combines a refined brushed-aluminium frame and diamond-grille front panel with dual 4 mm tempered-glass side panels for a showcase-ready appearance. Four pre-installed 140 mm fans deliver optimized airflow while keeping noise levels low. The case is engineered for high-performance and custom water-cooling builds with dual AIO support and room for pump and reservoir installation. Tool-free features — including an easy-release side panel, a patented graphics card slot clamp, removable brackets for fan and radiator mounting, and a detachable rear PSU bracket — simplify building and maintenance. Integrated dust filters, comprehensive cable-management options and adjustable graphics-card braces keep the interior tidy and accessible.

How to use
Release the side panel using the rear push button for tool-free access; the hinged tempered glass can swing open or be removed entirely for easier component installation. Mount fans and radiators on the removable brackets outside the case if preferred, then slide the assemblies into place. Install the PSU using the detachable rear bracket to simplify insertion. Secure the graphics card with the patented slot clamp and adjust the multifunction cover position to accommodate ATX or EATX motherboards while hiding cables. Connect ARGB and fan headers to the integrated controller and motherboard as required, and use PWM control to manage fan speeds for different workloads.
Recommendations
For best thermal performance, use high-quality 140 mm fans or a 420 mm front radiator combined with a 360 mm top radiator when planning dual AIO or custom-loop cooling. Use the removable dust filters and accessible panels for regular cleaning and route cables through the Velcro grommet channels for optimal airflow and a neater build.
