## Long description

The CHIEFTEC BE-10B-300 is a Small Form Factor (SFF) computer case from the Uni Series designed for compact office and desktop builds. The black chassis has a total volume under 9 liters and supports Mini-ITX and Micro-ATX motherboards. It ships with a pre-installed 300 W 80 PLUS Bronze power supply and an 80 mm front fan, and the front panel provides four USB ports for convenient connectivity.
Advantages
The BE-10B-300 combines a very compact footprint with practical expandability: it supports Slim ODD and provides dedicated mounting for 2.5" and 3.5" drives as well as a 5.25" bay. The included 300 W 80 PLUS Bronze PSU ensures basic energy efficiency out of the box, while the pre-installed 80 mm fan helps maintain airflow in a small enclosure. The front I/O with two USB 2.0 and two USB 3.2 Gen 1 Type-A ports offers balanced connectivity for peripherals.
