PC case CORSAIR FRAME 4000D RS ARGB Midi Tower Black — ATX/Micro-ATX/Mini-ITX, tempered glass, ARGB fans, up to 370 mm GPU

FRAME 4000D is a modular mid-tower PC case designed for versatile builds and next-generation GPUs. The case supports multiple radiator and fan configurations, offers a cable shroud and anti-sag GPU stabilization arm, and includes modern front I/O such as USB-C. It is compatible with reverse-connector motherboards and provides room for extensive cooling setups to accommodate demanding components.

Advantages

The FRAME Modular Case System enables extensive customization of the case structure and components without the need for proprietary parts. A multi-point InfiniRail fan mounting system allows adjustable fan placement up to 200 mm in the front and 140 mm in the roof for targeted airflow. The case includes three RS120 ARGB PWM fans and supports up to ten 120 mm fans simultaneously or up to twelve 120 mm fans with additional options. Dual 360 mm radiator support gives flexibility for high-performance liquid cooling, while the included GPU anti-sag arm and cable shroud help maintain a clean, stable interior.

How to use

Plan your build by selecting the motherboard and GPU that fit the FRAME 4000D dimensions and connector orientation. Use the InfiniRail system to position fans where you need targeted airflow and install radiators in the front, roof or side mounting locations depending on your cooling priorities. Connect the included RS120 ARGB PWM fans to a single 4-pin PWM header and a +5V ARGB header on a compatible motherboard for power and lighting control. Route cables behind the shroud to maintain unobstructed airflow and secure the GPU with the provided anti-sag stabilization arm.

Recommendations

For optimal cooling performance, combine front or side intake radiators with roof or rear exhaust, and ensure fans are positioned using the InfiniRail to avoid airflow conflicts. Verify motherboard connector orientation and available headers for PWM and +5V ARGB before finalizing component selection.
