Asus ROG Strix Helios II White E-ATX Mid Tower Case

The ASUS ROG Strix Helios II White Edition is a premium E-ATX mid-tower gaming case engineered for builders who want a showcase-worthy rig without compromising on thermal performance. At its core, four pre-installed 140×28 mm performance fans work in concert to deliver strong, consistent airflow at a measured 29 dB(A) noise level — keeping your components cool while the system stays relatively quiet during everyday use. The exterior makes an immediate impression. Dual 4 mm-thick tempered glass side panels sit within a refined brushed-aluminium frame, exposing your build from nearly every angle. The front panel is crafted using high-precision CNC milling and an anodising process, resulting in a diamond-grille design accented by diagonal slashes inspired by motorsport aesthetics. A 3D-structured front filter sits behind the grille to balance airflow restriction and dust protection simultaneously. Inside, the Helios II accommodates motherboards from Mini-ITX all the way up to E-ATX, with support for graphics cards up to 450 mm in length — making it compatible with the most demanding multi-fan GPU designs on the market today. A tool-free graphics card slot clamp snaps your GPU firmly in place, eliminating the need for a screwdriver during installation. A rear-detachable PSU bracket allows you to fit your power supply outside the chassis first, then slide the entire assembly back in, simplifying what is often an awkward step. CPU cooler clearance is rated at 190 mm, and the PSU bay accepts units up to 220 mm long. Liquid cooling builders will appreciate front radiator support up to 420 mm (accommodating 120 mm, 140 mm, 240 mm, 280 mm, 360 mm, and 420 mm units), top support up to 360 mm, and rear support for 120 mm or 140 mm radiators. Up to seven fans can be installed in total across front, top, and rear positions. A multifunction cover with adjustable GPU braces and a dedicated cable cover keep the visible interior tidy, while a cable grommet bar with three large straps manages routing on the back side of the motherboard tray. The front I/O panel includes two USB 3.2 Gen 2×2 Type-C ports (20 Gbps each), four USB-A 3.2 Gen 1 ports, and a headphone/microphone combo jack. A dedicated ARGB button controls the integrated Aura Sync-compatible lighting controller, while a separate PWM button lets you cycle fan speeds on the fly. X-shaped woven fabric carry straps, tested to support loads up to 50 kg, make transporting the system to a LAN event straightforward. Storage options include up to two 3.5-inch HDDs and four 2.5-inch SSDs, giving you room to grow your drive array. Dust filters on the front, top, and bottom complete the protection package. — Verified Specifications — Model: ROG-STRIX-HELIOS-II-WHITE | Form Factor: E-ATX / ATX / M-ATX / M-ITX | Colour: White | Material: Aluminium, Tempered Glass | Expansion Slots: 8 + 2 | Max CPU Cooler Height: 190 mm | Max GPU Length: 450 mm | Max PSU Length: 220 mm | Pre-Installed Fans: 4 × 140×28 mm (29 dB(A)) | Max Fan Support: 7 | Max Radiator (Front): 420 mm | Storage: 2 × 3.5″ HDD, 4 × 2.5″ SSD | Front I/O: 2 × USB 3.2 Gen 2×2 Type-C (20 Gbps), 4 × USB-A 3.2 Gen 1, Audio | Dust Filters: Front, Top, Bottom | Warranty: 2 Years
