CORSAIR Mid-tower Geh Midi Frame 4000d Black

The CORSAIR FRAME 4000D Midi Tower in black is a PC case engineered for high airflow and flexible modular upgrades. It supports Mini-ITX, Micro-ATX, ATX and EATX motherboards, accepts ATX power supplies, and provides mounting for 2x 3.5" drives and 2x 2.5" drives. The case accommodates multiple fan sizes (120 mm, 140 mm and up to 200 mm in the front) and offers extensive radiator support, making it suitable for demanding cooling configurations while maintaining a compact 239 mm × 490 mm × 486 mm footprint.

Advantages

FRAME 4000D delivers improved airflow with a 3D Y-pattern steel front panel that reduces resistance and increases intake efficiency. The FRAME Modular Case System enables modular upgrades such as alternative motherboard trays or front I/O panels. A steel multi-point InfiniRail fan mounting system allows precise placement of front and roof fans (up to 200 mm in front, 140 mm in roof). The case includes a GPU anti-sag stabilization arm, cable shroud for neat cable management, and modern front I/O with USB 3.2 Gen 2 Type-C and two USB 3.2 Gen 1 Type-A ports.

Suitable for

• Custom gaming PCs that require strong airflow and GPU support
• Water-cooled systems using dual 360 mm radiators or multiple 120 mm fans
• Upgradable builds that benefit from modular components and cable management
• Workstations needing support for larger motherboards (EATX) and multiple storage drives

How to use

Install the desired motherboard (Mini-ITX to EATX) onto the tray and route power and data cables through the cable shroud and rear routing channels to maintain unobstructed airflow. Choose fan placement using the InfiniRail mounting system—slide the rail to position front and roof fans where needed, and install radiators in the front, roof or side mounts according to your cooling plan. Secure the graphics card and use the included anti-sag arm to prevent PCIe slot strain. Connect front-panel USB and audio to the motherboard headers using the provided cables.

Recommendations

For optimal cooling, configure a balanced intake and exhaust setup (for example, multiple front intake fans with roof or rear exhaust) and use the flexible fan rail to position larger fans for targeted airflow. When installing reverse-connector motherboards from Asus, MSI or Gigabyte, ensure connectors are aligned to avoid cable obstruction and preserve the clean internal layout.
