The DeepCool MATREXX 40 3FS Micro-ATX case is a compact black micro tower designed for Mini-ITX and Micro-ATX builds. It features an edge-to-edge tempered glass side panel, front and top mesh for improved ventilation, and pre-installed tri-color LED fans to provide immediate airflow and basic lighting out of the box. The case supports multiple fan and radiator configurations and offers removable drive cages for up to two 3.5" HDDs and two 2.5" SSDs.

Advantages

The MATREXX 40 3FS combines strong cooling potential in a small chassis, with support for up to six 120 mm or four 140 mm fans and front/top radiators up to 280 mm. Three pre-installed 120 mm tri-color LED fans provide airflow and lighting without additional purchases. A tempered glass side panel gives a clean, finished look while the front and top mesh panels improve intake and exhaust airflow. The removable drive cage allows flexible storage layouts for both 3.5" and 2.5" drives.

How to use

Install a Mini-ITX or Micro-ATX motherboard and secure a bottom-mounted ATX-compatible power supply. Fit storage drives into the removable drive cage or 2.5" mounts as required. Connect the three pre-installed 120 mm fans to the available fan headers or included power connectors and route front I/O cables to the motherboard headers for USB access. If using liquid cooling, install compatible radiators at the front or top up to 280 mm. Reattach the tempered glass panel once all components are secured.

Recommendations

For optimal cooling balance, use the two front 120 mm fans as intake and the rear 120 mm fan as exhaust; keep the front and top mesh unobstructed. If installing multiple storage drives, consider using the removable drive cage to improve internal airflow. Ensure compatibility of radiator and GPU lengths with the Micro-ATX layout before final installation.
