Product information

Description

The Chieftec BM-25B-OP ATX Black is a mid-tower PC case compatible with ATX, Mini-ATX and Mini-ITX motherboards. Constructed from 0.7 mm SECC steel and finished in black, the chassis continues the Classic Series lineage with a refreshed front panel and internal improvements. The design supports multiple drive sizes and a variety of fan configurations to suit standard system builds.

Advantages

The BM-25B-OP offers a sturdy SECC-steel construction, tool-less drive installation kits and a compact, practical footprint (198 mm W x 465 mm D x 425 mm H). Front and rear fan support for several sizes allows flexible cooling setups, and multiple external and internal bays accommodate 5.25", 3.5" and 2.5" drives. Front I/O includes USB 3.2 Gen 1 Type-A and USB 2.0 ports for common connectivity needs.

How to use

Install a compatible motherboard (ATX, Mini-ATX or Mini-ITX) on the standoffs, fit the PSU and route cables through the available openings. Use the tool-less drive kits to secure 3.5" and 5.25" drives, and mount the 2.5" drive in the dedicated bay. Choose and install front and rear fans according to your cooling needs and connect them to the motherboard fan headers. Connect front-panel USB ports and power/reset switches to the motherboard headers following the board manual.

Usage recommendations

For balanced cooling and quiet operation, install a 120 mm front fan combined with a 120 mm or 90 mm rear exhaust. Use the tool-less bays to reduce assembly time and ensure cables are routed away from airflow paths to maintain optimal cooling performance.
