Case Corsair FRAME 4000D RS Modular white Mid Tower

Corsair FRAME 4000D RS

The Corsair FRAME 4000D RS case is a highly spacious modular ATX case, providing true design freedom and a clean look. The InfiniRail fan mounting system enables extreme flexibility in fan placement, and it is compatible with motherboards featuring Reverse Connector headers for elegant cable concealment behind the board.

CORSAIR’s new FRAME platform is based on modules that can be slid and swapped, allowing you to build an airflow and display environment tailored precisely to your needs. Careful cable management, convenient access to all components, and magnetic dust filters at every intake keep the system cool, clean, and tidy over time.

InfiniRail Fan Mounting System

Instead of predefined mounting holes, InfiniRail provides continuous mounting rails with multiple attachment points, so you can position fans exactly where you need them. Quickly sliding the rail—often tool‑free—allows a perfect fit for CPUs, graphics cards, and radiators.

Support for front fans up to 200 mm (and up to 140 mm on the top) allows you to channel targeted airflow to the most heat‑sensitive components and maximize performance while keeping noise low.

Dual 360 mm Radiator Support

The 4000D RS has three dedicated positions for 360 mm radiators—front, top, and side—so you can choose a single high‑performance AIO for CPU cooling, or a combination of two 360 mm radiators for advanced liquid‑cooling setups.

You can install up to ten 120 mm fans simultaneously to create controlled positive/negative air pressure, with continuous cool air intake and efficient heat exhaust even under sustained load.

Three RS120 Fans Included

The package includes three RS120 PWM fans with convenient daisy‑chain connectors to reduce cabling and enable fast, clean installation. Magnetic bearings reduce friction and wear, deliver long‑term quiet operation, and maintain an excellent balance between airflow and static pressure.

With PWM control via the motherboard you can set smart fan curves: quiet while browsing, and maximum performance during gaming or rendering.

Graphics Card Anti‑Sag

Every FRAME 4000D case comes with a graphics card stabilization arm (Anti‑Sag Stabilization Arm) that keeps the card level and straight, even with especially long and heavy models.

The arm relieves stress from the PCIe slot and protects the PCB from warping, with a simple adjustment mechanism to fit most cards on the market.

Maximum Cooling Flexibility

Tailor the cooling solution precisely to your needs: room for up to twelve 120 mm fans or a mix including 140 mm, support for two 360 mm radiators, and wide air channels with ventilated panels to maintain low temperatures.

Removable dust filters at the front, top, and bottom allow easy, quick maintenance, keeping the system clean and efficient over time.

Modern Front I/O Panel

On the front panel you’ll find fast USB 3.2 Gen 2 Type‑C, two USB 3.2 Gen 1 Type‑A ports, and a combined 3.5 mm headphone/microphone jack—exactly what you need to connect modern peripherals without reaching behind the case.

Accessible power and reset buttons, clear activity indicators, and broad compatibility with current motherboards round out a smooth, convenient user experience.
