Know before you buy
The InfiniRail™ system allows you to slide your fans along a rail rather than being restricted to fixed screw holes. This gives you much more flexibility in positioning your cooling fans to align perfectly with your specific hardware layout.
Yes, the 4000D RS is specifically designed to support reverse connector motherboards, such as ASUS BTF, MSI Project Zero, and Gigabyte Project Stealth. This allows you to hide your cables behind the motherboard tray for a cleaner, cable-free look in the main chamber.
The included anti-sag arm provides essential structural support for modern, heavy graphics cards. It helps prevent the GPU from drooping over time, which protects both the card and the PCIe slot from potential stress damage.
The case supports up to dual 360mm radiators simultaneously, allowing for high-end liquid cooling configurations. You can mount them at the front and top of the chassis to maximize thermal performance.
Yes, the 3D Y-pattern design is engineered to maximize airflow intake while maintaining a sleek aesthetic. By increasing the surface area and openness of the front panel, it allows the included RS120 ARGB fans to pull in more cool air for your components.
The case features a dedicated cable shroud and a spacious interior layout designed to keep your build looking tidy. Combined with the reverse connector motherboard support, it is significantly easier to manage and hide excess cables compared to standard mid-tower cases.
