The Corsair FRAME 4000D RS is a modular mid-tower PC case designed for clean, flexible, high-airflow desktop builds. With its FRAME Modular Case System, spacious interior, and InfiniRail Fan Mounting System, it gives builders more freedom to configure cooling, airflow, and internal layouts around their hardware.
The case includes three Corsair RS120 performance fans and supports up to 12 x 120mm fans, giving you strong airflow potential right out of the box. It also supports multiple radiator sizes, including up to 360mm radiators in the front, top, and side positions, making it suitable for both air-cooled and liquid-cooled gaming PCs.
Built for modern components, the FRAME 4000D RS supports Mini-ITX, Micro-ATX, ATX, and E-ATX motherboards, graphics cards up to 430mm, CPU coolers up to 170mm, and ATX power supplies up to 220mm. It is also compatible with reverse-connector motherboards, helping create a cleaner interior with fewer visible cables. A GPU anti-sag stabilisation arm, tempered glass side panel, modern front I/O, and dust filtration make it a practical and good-looking choice for performance PC builds.
