Easy Installation & Maintenance

ROG Strix Helios II White Edition is designed with multiple mechanisms to provide the smoothest building experience, even for DIY novices. Meanwhile, keeping your rig clean is made easy with built-in dust filters and easy access to all areas.

Tool-Free Side Panel Design

Pushing a button at the rear of the case releases one of the side panels for tool-less access to the interior. Its tempered glass is hinged on the bottom to swing away and rest at an angle, or you can remove the panel completely and set it aside while you tinker.

Modular Fan & Radiator Mounts

Two removable brackets let you easily mount fans and radiators before installing the whole assembly into the case, simplifying your building experience.

Patented Graphics Card Slot Clamp

A tool-free graphics card slot clamp makes your PC building faster and hassle-free with a simple snap that secures your GPU firmly in place.

Rear Detachable PSU Bracket

For easier installation, a rear bracket detaches from the case so that a power supply can slide right in.

Dust Filters

The 3D-structured front filter provides ample space for the front fans while providing optimized airflow and acoustics. It combines forces with removable filters on the top and underside to provide all-round protection from dust, making cleaning and maintenance easier.

Effortless Cable Management

Keep your build sharp and tidy with flexible covers and a comprehensive cable management system. A cable grommet channel features velcro to let you neatly organize two sets of cables.

A multifunction cover with graphics card braces cleverly hides cabling while providing sturdy support to graphics cards. Its position can be adjusted to accommodate an ATX or EATX motherboard.

The movable two-piece PSU shroud has a front cut-out to enable compatibility with the OLED panels of ROG Thor or other power supplies.
