Product information

Description

This PC chassis front panel supports installation of 2 external 5.25" drives, 1 external 3.5" drive and 3 internal 3.5" drives. Front I/O includes USB 2.0 and audio connectors placed for easy ergonomic access. The case also allows mounting up to three 120 mm fans and two 80 mm fans to provide effective airflow and thermal management.

Advantages

The layout combines multiple external and internal drive bays with conveniently located front connectors for simple access. The fan mounting options enable flexible cooling configurations to maintain stable operating temperatures. The front panel design balances expandability and usability.

Key specifications

  • External bays: 2 x 5.25", 1 x 3.5"
  • Internal bays: 3 x 3.5"
  • Front connectors: USB 2.0, audio
  • Fan support: up to 3 x 120 mm and 2 x 80 mm

How to use

Install optical or other 5.25" drives into the two external 5.25" bays and a compatible device into the external 3.5" bay. Mount hard drives in the three internal 3.5" bays and connect power and data cables to the motherboard and PSU. Connect front-panel USB 2.0 and audio cables to the corresponding headers on the motherboard. Fit cooling fans into available 120 mm and 80 mm positions, ensuring airflow direction matches your overall case ventilation plan.

Recommendations

Use quality fans matching the specified sizes (120 mm and 80 mm) and ensure proper cable routing to maintain unobstructed airflow. Verify motherboard front-panel headers for USB 2.0 and audio compatibility before installation.
