The ROG Strix Helios II is a premium mid-tower gaming chassis from ASUS Republic of Gamers, constructed with a brushed-aluminum front panel featuring a diamond-grille design and a noise-reducing 3D-structured filter. The case incorporates dual 4 mm-thick tempered glass side panels set within a streamlined aluminum frame, allowing for showcase builds and extensive airflow. It comes preinstalled with four 140 × 28 mm performance fans that balance high static pressure with low noise, and supports up to dual 360 mm radiators in the front and top mounts. Internally, the Helios II accommodates motherboards from ITX up to E-ATX form factors, graphics cards up to 450 mm in length (or 105 mm thick in vertical orientation), tower coolers up to 190 mm tall, and custom-loop water-cooling configurations, making it suitable for heavyweight components and advanced cooling setups.
Installation and maintenance are streamlined through multiple tool-free mechanisms, including one-key-release side panels, a patented PCIe slot clamp, and a detachable rear PSU bracket. Cable management is facilitated by 33 mm of routing space, dedicated rear cable clips, a multifunction cable cover, and a unified front-panel header to consolidate ARGB and PWM fan connections. The advanced I/O panel offers two 20 Gbps USB-C® ports with 60 W fast charging, four USB-A 3.0 ports, an audio jack, plus dedicated buttons for lighting and fan control. Available in both black and white finishes, the ROG Strix Helios II began shipping to select markets around September 2025, targeting enthusiasts seeking a balance of aesthetics, expandability, and ease of build.
