Chieftec BX-10B-OP computer case Tower Black

The CHIEFTEC BX-10B-OP is a compact black mini tower designed for small but capable PC builds. It supports Micro‑ATX and Mini‑ITX motherboards, standard ATX power supplies, one pre-installed 120 mm rear fan and room for up to six fans in total. The chassis accepts graphics cards up to 380 mm in length and provides bays for both 2.5" and 3.5" drives, offering flexible storage options in a space‑efficient enclosure.

Advantages

The BX-10B-OP combines a subtle matte black exterior with practical internal layout, supporting multiple cooling configurations including top mounts for 120 mm and 140 mm fans. Its compatibility with standard ATX PSUs and compact m-ATX/Mini‑ITX motherboards makes installation straightforward, while the side window allows component visibility. Made from SPCC carbon steel, the case balances sturdiness and weight for desktop use.

How to use

Install a Micro‑ATX or Mini‑ITX motherboard and a standard ATX power supply into the case, mount storage drives into the provided 2.5" and 3.5" bays, and fit the graphics card up to 380 mm in length. Connect the front I/O panel to the motherboard headers and route cables to maintain airflow. Configure additional fans on the top or front positions as needed to achieve the desired cooling performance.

Recommendations

For balanced cooling and noise, use the pre-installed 120 mm rear fan together with one or two top-mounted 120/140 mm fans and keep cable routing tidy to avoid airflow obstruction. Verify GPU length and PSU depth before final assembly to ensure component compatibility.
