The Corsair FRAME 4000D RS is a versatile, fully-modular mid-tower PC case designed for high-performance PC builds requiring superior airflow and extensive customization. Featuring the innovative InfiniRail™ Fan Mounting System, this chassis allows you to precisely position multiple fans (up to 200mm front, 140mm top) for optimized cooling tailored to your components.

Included are three high-quality RS120 PWM fans which balance powerful airflow with quiet operation via magnetic dome bearings. The spacious interior supports Mini-ITX, Micro-ATX, ATX, and larger E-ATX motherboards (up to 305 x 277 mm), including reverse-connector models from ASUS, MSI, and GIGABYTE.

Designed with airflow in mind, the 3D Y-pattern steel front panel offers up to 12% more airflow than previous models. The FRAME 4000D RS supports dual 360mm radiators simultaneously on front, top, and side, giving unparalleled liquid cooling flexibility. Other practical features include a GPU anti-sag stabilization arm, multiple SSD/HDD mounts, integrated cable shrouds, and dust filtration for a clean and efficient build.

Connectivity is modern and convenient with front-panel I/O featuring 1x USB 3.2 Gen 2 Type-C, 2x USB 3.2 Gen 1 Type-A, and audio in/out ports. The tempered glass side panel elegantly showcases your components while the steel right panel adds durability. With support for vertical GPU mounting (riser card sold separately) and ample internal space, this case is perfect for gamers, enthusiasts, and modders alike.

Backed by a 2-year Corsair warranty, the FRAME 4000D RS in stunning white color blends premium build quality, modular expandability, and advanced cooling options into a stylish and functional PC case.
