CORSAIR Frame 4000D RS ARGB E-ATX Mid Tower Case

The CORSAIR Frame 4000D RS ARGB is a fully-modular mid-tower PC case engineered for builders who demand flexibility, clean aesthetics, and serious thermal performance. Built around the FRAME Modular Case System, it lets you swap out the motherboard tray, front I/O panels, and other structural components as your build evolves — no need to replace the entire chassis when your requirements change. At the heart of its airflow strategy is the InfiniRail Fan Mounting System, a steel multi-point sliding rail that lets you position fans precisely where airflow is needed rather than locking you into fixed mounting positions. The front and roof rails support fans up to 200mm (140mm in the roof), giving you exceptional targeting flexibility for both intake and exhaust. Cooling headroom is substantial. The case provides three dedicated 360mm radiator mounting locations — front, roof, and side — and supports up to 10 x 120mm fans simultaneously across those positions. Maximum total fan support reaches 12 x 120mm, making this chassis equally at home with air-cooling towers up to 170mm tall or high-end liquid cooling loops. Three RS120 ARGB PWM fans come pre-installed, each daisy-chainable so the entire set is controlled through a single 4-pin PWM connector and one +5V ARGB header on a compatible motherboard — no separate lighting controller required. ARGB lighting can be managed directly through your motherboard's software ecosystem. The case is fully compatible with reverse-connector motherboards from Asus, MSI, and Gigabyte, routing all power and data connectors to the rear of the tray for a completely unobstructed view of your components. A built-in GPU Anti-Sag Stabilization Arm keeps graphics cards level, protecting the PCIe slot over long-term use. A dedicated cable shroud hides excess or overly long cables, maintaining a tidy interior at all times. **Verified Specifications:** - Form Factor: E-ATX, ATX, Micro-ATX, Mini-ITX - Colour: Black - Materials: Steel, Plastics, Tempered Glass - Pre-Installed Fans: 3 x RS120 ARGB PWM - Max Fan Support: 12 x 120mm - Radiator Support: Front/Roof/Side 360mm; also 280mm, 240mm, 140mm, 120mm - Max GPU Length: 430mm - Max CPU Cooler Height: 170mm - Max PSU Length: 220mm - Drive Bays: 2 x 3.5" HDD, 2 x 2.5" SSD - Expansion Slots: 7 - Dust Filters: Top - Front I/O: 1 x USB 3.2 Gen 2 Type-C, 2 x USB 3.2 Gen 1 Type-A, 1 x combo audio/mic jack - Warranty: 2 Years - SKU: CC-9011296-WW
