ASUS Republic of Gamers Announces ROG Strix Helios II Chassis

ASUS Republic of Gamers (ROG) today announced the ROG Strix Helios II, a mid-tower gaming PC case with premium luster and efficient cooling in a design that offers plenty of elbow room for the building process. The chassis features aluminum exterior elements, an optimized internal layout, and incredible thermal efficiency to ensure readiness for heavyweight gaming.

The Helios II is packed with connectivity and DIY-friendly features. Users get enough front ports to connect all their peripherals and can even top up their mobile devices with the front panel’s 60-watt USB-C® fast charging. Effortless assembly is enabled thanks to the Helios II’s spacious design, wealth of tool-free installation features, and cable management optimizations. Combine these perks with this case’s aesthetics and cooling capabilities, and users will find the ROG Strix Helios II is in a class all its own.

Compelling looks 

Available in black or white, the ROG Strix Helios II carefully balances a bold gaming aesthetic, with innovative design flourishes. Its diamond-grille aluminum front panel stands out with a distinctive slat design and striking one-tone color scheme. Users with an all-white battlestation should check out the white ASUS GeForce RTX 50 Series graphics cards to keep such a rig color-coordinated inside and out.

The Helios II’s front panel makes a bold statement with a grille of diamond-pattern slits that lets a wide stream of cooling air come in. This pattern draws attention to the case’s aluminum elements and stylish flourishes like the front panel’s 3D-embossed ROG logo. These premium details produce a proud, performance-driven look that fits well in any serious PC gamer’s setup. And the case’s tempered glass side panels will show off internal components and any RGB a user wants to glow up the room with, letting them personalize their ROG Strix Helios II experience.

The front panel’s slat design helps a PC breathe. And thanks to a noise-reducing 3D-structured filter behind the panel, users can enjoy the front fans’ cooling power without hearing excessive fan noise. 

This case comes preinstalled with four 140mm fans, each with extra-thick 28mm frames. Compared to standard models on the market, these fans push a similar amount of air at much quieter noise levels, and they can kick into higher gear for maximum air-pushing power. Three fans occupy the front, while one is located in the back of the chassis to expel hot air.

The case offers dual 360mm radiator support via mounting points on its front and top panels. This makes it great for ultra-quiet liquid-cooling setups, such as a top-of-the-line rig with an ROG Astral LC GeForce RTX™ 5090 graphics card and ROG Ryuo IV SLC 360 ARGB AIO CPU cooler.

Ready for heavy-duty gamers, DIY enthusiasts

This chassis is a gaming PC builder’s dream. With capacity for cards up to 450mm long, it can fit the largest NVIDIA® GeForce RTX™ 50 Series graphics cards on the market, in either vertical or horizontal orientations. It can also house a custom liquid-cooling setup with ease, and it’s EATX compatible — so large motherboards like the Crosshair X870E Extreme are easily accommodated.

The large size of the chassis lends itself to easy DIY tinkering. With so much space, users do not have to worry about scraping their knuckles on tightly packed parts. Plus, there are features to streamline building efforts. The one-key-release side panel design lets users pop both sides off of the case without tools.

The Helios II also features a patented tool-free PCIe® mount at the rear, making expansion card installation a cinch. And the rear detachable PSU bracket ensures that sliding power supply units in and out is just as easy.

Those preferring a tidy rig will appreciate the 33mm of cable routing room. Internally, the unified front panel header makes attaching cables easy, while the case’s cable-management cover hides unsightly cords from view. Outside, rear cable clips provide an easy way to manage peripheral cords, if users have wired mice, keyboards and headsets hooked up.

For even more cable consolidation, the case’s ARGB and fan controller gives users one-stop control over a maximum of six ARGB components and six PWM fans. This streamlines lighting and cooling management for maximum ease of DIY setup.

Quality-of-life features for gaming greatness

The Helios II features a robust selection of front I/O options, giving users effortless access to essential ports. These include four USB 3.0 Type-A ports and two USB 20Gbps Type-C® ports with data transfer and 60W fast-charging capabilities. Users can hook these ports up to a compatible motherboard to turn a PC’s front panel into a convenient fast-charging station. There’s also a headphone-microphone jack as well as dedicated power, reset, and LED control buttons.

Case straps help set the ROG Strix Helios II apart from other cases in the quality-of-life department. They are woven on top of the chassis and built for easy gripping, thanks to their dual X-shaped structure. This makes it easy to transport the chassis after assembly, and it also makes it easier to take a gaming rig to a LAN party. Or, if a user is reorganizing their gaming space and needs to move their rig around a room or to another place in the home, the straps easily facilitate any move.

The ultimate case for gaming

The ROG Strix Helios II is the ultimate case for gamers who want a wealth of features and style. Between its unique diamond-grille design, various DIY-friendly optimizations, handy carrying straps, and expansive space for just about any component, it’s an obvious choice for anyone truly invested in leveling up their ROG PC gaming battlestation.
