Corsair FRAME 4000D RS ARGB CC-9011296-WW PC case

FRAME 4000D RS ARGB mid-tower

The Corsair FRAME 4000D RS ARGB is a steel and tempered glass ATX mid-tower built for high-airflow custom builds. It supports Mini-ITX through E-ATX motherboards up to 305 by 277 millimetres. Three RS120 ARGB fans are included and the InfiniRail mounting system lets you reposition fans without tools. Dust filters on the bottom, front and side keep internals clean.

Modular upgrade for airflow-focused builders

The fully modular interior replaces fixed drive cages and rigid fan brackets with sliding rails and removable panels. This layout makes it worth switching when you need to fit multiple 360 millimetre radiators or long graphics cards up to 430 millimetres. Two 3.5 inch and four 2.5 inch drive bays remain accessible after the change. Compatibility with reverse-connector motherboards such as ASUS BTF and MSI Project Zero removes cable routing compromises.

Sustained load behaviour with dual radiators

Under continuous load the case can run front and top 360 millimetre radiators simultaneously while the side panel accepts another 360 millimetre unit. The included 120 millimetre fans feed cool air through unrestricted mesh, and the GPU anti-sag arm prevents PCB flex during long sessions. CPU cooler clearance of 170 millimetres and PSU length up to 220 millimetres ensure high-wattage components stay within limits without throttling.
