The ROG Strix Helios II is the gaming PC case for ambitious DIY builders and hardcore gamers alike

A PC case for a cutting-edge gaming rig has its work cut out for it in 2025. Not only does it need the installation room for top-tier components, but it should also be ready to move serious air. And it should put a spotlight on your build’s internals while adding a stylistic element of its own. Many chassis options struggle to hit all these notes at once, but that’s where the ROG Strix Helios II case excels. Packing premium luster and efficient cooling in a design that offers plenty of elbow room for your build process, this chassis is ready to look sharp and play cool. Its aluminum exterior elements, optimized internal layout, and incredible thermal efficiency ensure the case is ready for heavyweight gaming.

The Helios II goes hard when it comes to connectivity and DIY-friendly features, too. You’ll get enough front ports to connect all your peripherals and even top up your ROG Phone 9 with the front panel’s 60W USB-C fast charging support. Also expect an effortless assembly process with the Helios II’s spacious design, wealth of tool-free part installation features, and cable management optimizations. Combine these perks with the Helios II’s aesthetics and cooling capabilities, and you’ll find the ROG Strix Helios II is in a class all its own.

The look your gaming PC needs

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. The options are black or white — the choice is yours. But if you’re rocking an all-white battlestation, check out our white RTX 50 Series graphics cards so you can keep your 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. Combined, these premium details produce a proud, performance-driven look that’ll fit well in any serious PC gamer’s setup. And the case’s tempered glass side panels will show off your internal components and any RGB you want to glow up the room with, letting you personalize your ROG Strix Helios II experience.

Maximum cooling, minimum noise

The front panel’s slat design isn’t just for looks. It helps your PC breathe. There’s a noise reduction 3D-structured filter behind the panel, so you can enjoy the front fans’ cooling power while minimizing their sound output.

This case comes preinstalled with four 140mm fans, each with extra-thick 28mm frames. Compared to standard spinners on the market, they can push a similar amount of air at much quieter noise levels, and they can kick into higher gear for maximum air-pushing power. Three occupy the front while one stays in the back to push out 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 if you're building a top-of-the-line rig with an ROG Astral LC GeForce RTX 5090 graphics card and ROG Ryuo IV SLC 360 ARGB CPU cooler.

Ready for heavy-duty gamers, tidy PC builders, and DIY enthusiasts

This chassis is any gaming PC builder’s dream. With capacity for cards up to 450mm long, it can fit the largest NVIDIA 50 Series graphics cards on the market, supporting both vertical and horizontal installation. It’ll house your liquid-cooling setup with ease, too. And it’s EATX compatible, so when you have a large motherboard like the Crosshair X870E Extreme, this chassis is ready to give it a home.

That size lends itself to easy DIY tinkering. With so much space, you don’t have to worry about scraping your knuckles on tightly packed parts. But we’ve also built in features to streamline building efforts. Our one-key-release side panel design lets you pop both sides off the case without tools while sparing you the visual blight of bolts and hinges.

The Helios II 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 for installation purposes is a breeze.

Tidy rig builders have a lot to look forward to with the Helios II and its 33mm of cable routing room. Internally, the unified front panel header cuts down on cabling hassle, while the case’s cable management cover hides unsightly cords from view. Outside, the rear cable clips provide an easy way to manage your peripherals’ cords in the event you have wired gaming mice, keyboards, and headsets hooked up.

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

Quality-of-life features for gaming greatness

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

The Helios II's ergonomically optimized case straps really help set it apart from other cases in the quality-of-life department. They're woven on top of the chassis, built for easy gripping thanks to their dual X-shaped structure. We designed them to make your life easier in numerous situations. Most important is getting your new PC safe and sound to its home on your gaming desk after assembly. If you want to bring your rig to a LAN party, just grab and go. Getting a desktop to your car has never been easier. Or, if you’re reorganizing your home gaming space and need to move your rig around a room — or a house — you now have a truly safe way to handle your PC.

Lots of gamers feel a pang of fear when they lift their desktop, gripping the rectangular prism with the knowledge that one drop can spell doom for sensitive internal components. Fear no more: like the original ROG Strix Helios, the ROG Strix Helios II provides a smart and stylish solution to the age-old desktop transportation problem.

The ultimate case for ROG-approved PC 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, boatload of DIY-friendly optimizations, ergonomic carrying straps, and space for just about any component on the market, it's an obvious choice for anyone truly invested in leveling up their ROG PC gaming battlestation.
