ROG Strix Helios II
Striking Looks. Cool Moves.
ROG Strix Helios II is a premium mid-tower gaming case featuring dual tempered glass side panels, a refined aluminum frame, and a diamond grille front panel with a 3D-structured front filter. It comes pre-installed with four 140 x 28 mm performance fans, delivering optimized airflow and enhanced thermal performance for demanding gaming setups. Engineered for expandability and performance, it's ready for motherboards ranging from ITX to EATX and serious water-cooling setups as well - making it the perfect choice for a classic ROG showcase build.
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.
Ready For High-Performance Builds With Dual AIO Support
The ROG Strix Helios II is built to perform and primed for expansion, with ample space for GeForce RTX™ 5090 graphics cards or hardcore water-cooling setups. It can handle a ROG Ryuo IV SLC 360 ARGB AIO cooler and the 360mm radiator of the ROG Astral LC GeForce RTX 5090 at the same time. It features support for radiators up to 420mm in the front and 360mm at the top, with room reserved for installing the pump and reservoir of a custom loop.
Easy Installation & Maintenance
ROG Strix Helios II 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.
Front I/O Panel
The Helios II includes two USB 20Gbps Type-C ports with support for 60-watt fast charging where compatible.
ARGB Lighting Control
