Manufacturer: CORSAIR
Street Price: 4000D WOOD RS $130 USD | 4000X RS $140 USD
The CORSAIR FRAME 4000X RS and CORSAIR FRAME 4000D WOOD RS arrive as the latest entries in CORSAIR’s evolving FRAME family, expanding a platform that’s clearly aimed at modern DIY builders who value flexibility as much as aesthetics. Sitting firmly in the mid-tower category, both cases build on the underlying FRAME 4000 chassis, introducing fresh design directions while retaining the core philosophy of adaptability and performance. Whether it’s the RGB-forward styling of the 4000X RS or the more refined, natural look of the WOOD RS, these additions broaden the appeal of the series without straying from its enthusiast roots.
A defining feature of these new models is just how modular they are. Built around the FRAME Modular Case System, both cases allow users to swap out panels, adjust internal layouts, and tailor the chassis to suit specific hardware or visual preferences. This goes beyond simple customisation—components like front panels, motherboard trays, and I/O modules can be reconfigured or replaced entirely, making the case feel more like a platform than a fixed enclosure. For builders who like to tweak, upgrade, or completely reinvent their systems over time, this level of flexibility is a major selling point.
That modularity is paired with a strong focus on cooling and airflow. Both cases support extensive fan and radiator configurations, including multiple 360mm radiator mounting positions and up to 13 fan mounts throughout the chassis. CORSAIR’s InfiniRail fan mounting system further enhances this by allowing precise fan placement without the constraints of fixed mounting points, giving builders fine control over airflow paths. Out of the box, both variants come equipped with RS120 fans to ensure solid thermal performance from the start, while features like tempered glass panels and PSU shrouds keep builds clean and showcase-ready.
In this review, we’ll be taking a closer look at what these cases bring to the table in practice—exploring their features in detail, building a full system inside each chassis, and putting their cooling capabilities to the test to see how they perform in real-world use.
