Premium Design & Aesthetics

ROG Strix Helios II is made for showcase builds with dual 4mm-thick tempered glass side panels fitted in a refined brushed-aluminum frame. The aluminum front panel, featuring a diamond grille design, is manufactured using high-precision CNC milling technology and an anodizing process. The diagonal slashes on the front are inspired by race car elegance and individuality to make the Helios II unique. With rounded edges, a streamlined shape and hidden seams, this chassis is sleeker than ever.

Four Pre-Installed Performance Fans

The Helios II is designed to balance performance and acoustics: Four pre-installed 140mm fans with 28mm frames deliver strong airflow while maintaining a low 29 dB(A) noise level.

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.

Multifunction Cover

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.

PSU Shroud

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.

Cable Cover

A cable cover conceals unsightly wiring, resulting in a clean and organized build. In addition, the Helios II provides versatile cable management with a cable grommet bar featuring three large straps for two sets of cables.

Rear Cable Clip

Rear cable clips help ensure clean cable management.

Ergonomic Case Straps

Easily carry your prized build to LAN parties with ergonomically X shape woven fabric straps that combine style and comfort, rigorously tested to support up to 50kg for reliable transport.

Embossed Emblem

Signature details, majestic proportions and a sense of elegant power converge on a gleaming aluminum ROG logo that stands proud amid diamond-shaped grilles - a nexus of inspiration for all.
