🚀 Say Goodbye to Limitations: The New Era of Modular PC Building
The CORSAIR 4000D chassis is an iconic name in the world of PC builders. It is synonymous with excellent airflow and clean design. But now, the brand has raised the standard with the launch of the FRAME 4000D RS series.
If you are looking for a tower that combines elite thermal performance, impeccable aesthetics, and unprecedented modularity, the FRAME 4000D RS is undoubtedly the new candidate for the ultimate case for your next setup.
đź’ˇ Three Defining Key Points: Maximum Innovation
The “RS” (Reverse Connector Support) version is not a simple update; it is a redesign that embraces the most modern trends in PC construction:
1. The InfiniRail™ Fan Mounting System
Forget fixed rows of fan holes. The InfiniRail™ is a steel rail mounting system that allows you to slide and adjust the position of your fans and radiators with millimeter precision.
- Flexibility: Place your 200mm, 140mm, or 120mm fan exactly where you need it most to direct airflow to your components.
- Compatibility: It seamlessly adapts to complex liquid cooling setups without interfering with the motherboard or RAM.

2. NATIVE Support for Reverse Connector Motherboards (BTF/Project Zero)
This is the big game-changer. The FRAME 4000D RS is designed to be compatible with new reverse connector motherboards (such as ASUS BTF, MSI Project Zero, or GIGABYTE PROJECT STEALTH).
- What does this mean? All power and data ports on the motherboard (24-pin, CPU, SATA, etc.) connect behind the tray.
- Result: An interior view completely free of cables, with only the graphics card and cooling visible, offering a minimalist and professional aesthetic.

3. The 3D Y-Pattern Airflow Front Panel
The heart of the performance is its airflow. Corsair has optimized the perforated steel front panel with a three-dimensional “Y” pattern. This design ensures a cold air path with minimal restriction, significantly enhancing overall thermal performance.
