The fully modular Corsair Frame 4000D RS ARGB mid‑tower case delivers easy personalization, powerful cooling, and a clean look. With the InfiniRail fan mounting system, three included RS120 ARGB fans, support for up to three 360 mm radiators, and compatibility with back‑connect motherboards, you can build a sleek, efficiently cooled PC with modern front I/O including USB‑C.
Fully modular design unlocks near‑limitless customization — from quick swapping of panels and accessories to expanding the front I/O with more ports. The case adapts to your needs and scales with your build.
InfiniRail is a multi‑point steel sliding‑rail system that maximizes fan placement flexibility at the front and top. Together with three locations for 360 mm radiators (front, top, side) and support for up to 10× 120 mm fans, you get targeted airflow without compromise.
- 3× RS120 ARGB PWM in the box — fans can be daisy‑chained, no separate controller required.
- Simple hookup — just one 4‑pin PWM and one 5V ARGB header on a compatible motherboard.
- Clean cable management — cable shroud and full compatibility with back‑connect motherboards (Asus, MSI, Gigabyte).
- GPU anti‑sag bracket — protects the PCIe slot and keeps the graphics card level.
- Modern front I/O — USB 3.2 Gen 2 Type‑C, 2× USB 3.2 Gen 1 Type‑A, combined 3.5 mm audio mic.
- Color — Black, an elegant look for any build.
