Chieftec UNC-409S-B Computer Case Rack Black 400 W

The Chieftec UNC-409S-B Rack Black is a compact 4U rackmount computer case designed to fit ATX and Micro ATX motherboards while keeping a short depth of 482 mm. Constructed from 1.2 mm SECC steel and supplied with a 400 W power supply, the chassis combines a space-saving footprint with robust protection for internal components and supports both 2.5" and 3.5" drives.

Advantages

Its 1.2 mm SECC steel construction provides structural strength and long-term durability. The shallow 482 mm depth makes the case suitable for racks with limited depth without sacrificing ATX compatibility. The front panel includes two USB 3.1 ports for fast external connectivity, and fan mounting points accommodate two 120 mm fans at the front and two 80 mm fans at the rear to support airflow and cooling.

How to use

Install an ATX or Micro ATX motherboard onto the internal standoffs, fit the included 400 W power supply into the designated bay, and mount storage devices in the 2.5" or 3.5" drive positions. If additional cooling is required, install up to two 120 mm fans in the front and up to two 80 mm fans in the rear fan positions. Connect the front-panel USB 3.1 ports to the appropriate motherboard header for full functionality.

Recommendations

For optimal cooling and longevity of components, use at least one front 120 mm intake fan and one rear 80 mm exhaust fan. Ensure rack depth clearance of at least 482 mm before installation and verify compatibility of GPU and other expansion cards with the available internal depth.
