The CHIEFTEC BE-10B-300 is a Small Form Factor (SFF) computer case from the Uni Series designed for compact office and desktop builds.

Advantages

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.

Use the front USB ports for keyboard, mouse and external drives. Ensure the 80 mm fan is unobstructed to maintain airflow; cable-manage inside the small chassis to avoid blocking vents. Place the case on a stable, flat surface with sufficient space for air intake and exhaust.

Recommendations

For reliable operation in compact builds, pair the BE-10B-300 with low-power CPUs and single-slot graphics or integrated graphics solutions. Regularly check and clean the 80 mm fan and ventilation openings to preserve cooling performance.
