Asus ROG Strix Helios II Mid-Tower Case with Dual Tempered Glass – ROG STRIX HELIOS II GX601S BLACK / WHITE

ROG Strix Helios II: Striking Looks Meets Ultimate Performance

The ROG Strix Helios II is a premium EATX mid-tower gaming case designed specifically for showcase builds and enthusiast-grade hardware. It evolves the legendary Helios lineage with a refined brushed-aluminum frame, dual 4mm-thick tempered glass side panels, and a revolutionary diamond-grille front panel. This new design features a high-precision CNC milled pattern that works in tandem with a 3D-structured filter to support massive airflow without compromising on aesthetic elegance. The front panel also integrates Aura Sync ARGB lighting, providing a customizable visual centerpiece that signals the power contained within.

Superior Thermal Engineering and Airflow

At the heart of the Helios II thermal strategy are four pre-installed 140mm performance fans. These are not standard case fans; they feature a thicker 28mm frame that delivers a massive 103 CFM of airflow and 2.3 mmH2O of static pressure. Despite this raw cooling power, the fans operate at a whisper-quiet 29 dB(A) noise level. For enthusiasts pushing the limits of modern CPUs and GPUs, the chassis provides comprehensive support for extreme water cooling. You can mount a 420mm radiator in the front and a 360mm radiator at the top simultaneously, making it one of the few mid-tower cases capable of housing dual high-performance AIO solutions or complex custom loops with dedicated pump and reservoir space.

Engineered for the Modern DIY Experience

Building in the ROG Strix Helios II is a streamlined, premium experience designed to satisfy both veteran builders and newcomers. It features a tool-free side panel design where a simple push of a rear button releases the tempered glass panels. The panels are hinged at the bottom to prevent accidental drops, allowing them to swing away safely. The internal layout supports massive EATX motherboards and graphics cards up to 450mm in length, such as the latest NVIDIA GeForce RTX 5090 series. To manage these heavy components, ASUS integrated a patented graphics card slot clamp and an adjustable multifunction cover with built-in GPU braces, ensuring your hardware remains perfectly level and secure.

Advanced Connectivity and Intelligent Control

The front I/O panel of the Helios II is equipped for the future of peripherals. It features two USB 3.2 Gen 2×2 Type-C ports capable of 20Gbps data transfer speeds. When paired with compatible motherboards, these ports support up to 60W fast charging, allowing you to charge laptops or smartphones directly from your case. The panel also includes four USB-A 3.2 Gen 1 ports and dedicated hardware buttons for ARGB lighting cycles and PWM fan speed control. This allows you to toggle between silent operation during work and maximum airflow during intense gaming sessions with a single physical press, bypassing the need for software intervention.

Effortless Cable Management and Mobility

Maintaining a clean aesthetic is made easy with the Helios II cable management system. With 33mm of space behind the motherboard tray and a dedicated cable grommet channel with velcro straps, organizing thick power cables is effortless. The multifunction cover and PSU shroud hide the complexity of the build, leaving only the primary components on display. For those who attend LAN parties or need to move their rig, the Helios II retains the signature ROG woven fabric straps. These ergonomic X-shaped straps are rigorously tested to support up to 50kg, ensuring your prized build can be transported safely and comfortably without straining the chassis frame.
