Corsair FRAME 4000D RS Modular Midi Tower PC Gaming Case - Black - CC-9011312-WW

The Corsair FRAME 4000D RS is a modular mid-tower case built around user-configurable panels and mounting options, finished in black. Its InfiniRail fan mounting system accommodates both 120mm and 140mm fans without separate brackets, adapting to whatever cooling you choose. A high-airflow front panel and roomy interior make it a practical, flexible foundation for a modern build.

Modular by Design

The FRAME series is built around modularity, with panels, brackets and mounting positions that can be reconfigured rather than fixed at the factory. That means the case adapts as your build changes, instead of forcing the build to work around the chassis. Tool-free panel removal makes accessing the interior quick during assembly and later maintenance.

InfiniRail Fan Mounting

Corsair's InfiniRail system uses adjustable rails rather than fixed screw holes, so the same mounting position accepts either 120mm or 140mm fans without adapters or separate brackets. That removes one of the more irritating constraints in case design, where choosing 140mm fans often means finding they simply will not fit. Fan positions can also be shifted along the rail to clear tall memory or a large air cooler.

Airflow and Capacity

A high-airflow front panel lets intake fans draw air freely rather than fighting a restrictive fascia, which is the single biggest factor in case cooling performance. The mid-tower interior accommodates standard ATX motherboards, long graphics cards and radiator mounting for liquid cooling. Cable routing channels and tie-down points behind the motherboard tray keep the visible side of the build tidy.
