CORSAIR FRAME 4000X RS Midi-Tower Case with window, with RGB lighting, Black

The CORSAIR FRAME 4000X RS Mid-Tower PC Case, Black supports ATX, E-ATX, Micro-ATX and Mini-ITX motherboards for desktop and gaming builds. Its high-airflow front panel ventilates the components inside. Cooling support covers both air and liquid configurations, so either approach can be used. Graphics cards up to 430 mm long fit within the chassis — a specific clearance limit worth checking before choosing a card. The modular design also allows the internal layout to be adjusted.

Steel and plastic construction is paired with a tempered-glass side panel that keeps the installed components visible. Cable-management features provide routing options inside the enclosure. Dust filters help limit the amount of dust entering the case during operation. The bottom-mounted power supply position accepts ATX units, but the power supply must be purchased separately. Front-panel ARGB lighting is accompanied by an RGB control button and LED controller. Screws are included for assembly, providing mounting hardware alongside the chassis.
