Product information

Description

The PC Case Chieftec Midi Tower BS-20B-OP Black is a compact mid-tower enclosure designed to house Mini-ITX and Micro ATX systems while maintaining efficient airflow. Finished in black, the case offers support for multiple drive sizes including 2.5", 3.5" and 5.25" devices, and accepts an ATX power supply (power supply not included). The chassis includes a preinstalled rear 90 mm fan and provisions for additional front cooling, permitting balanced ventilation in a small footprint of 170 mm (W) x 329 mm (D) x 408 mm (H).

Advantages

The BS-20B-OP provides a space-efficient layout suitable for compact builds without sacrificing drive flexibility or ventilation options. Its support for several HDD/SSD sizes and a 5.25" bay allows for optical drives or other front-mounted devices. The included rear 90 mm fan and capacity for front fans improve heat dissipation for typical home or office configurations. USB connectivity on the front panel offers convenient access for peripherals.

Suitable for

Home or office compact desktop builds with Mini-ITX or Micro ATX motherboards
Systems requiring multiple internal drives (2.5" and 3.5") and an optional 5.25" device
Basic gaming or multimedia PCs where airflow and a small footprint are priorities
Upgrades or replacements for small form-factor cases that need ATX power supply compatibility

Key specifications

Form factor: Midi Tower compatible with Mini-ITX and Micro ATX motherboards
External dimensions (W × D × H): 170 mm × 329 mm × 408 mm
Weight: 4.49 kg
Drive bays: support for 2 × 3.5" bays and 2.5" drives plus 1 × 5.25" bay
Cooling: 1 × rear 90 mm fan preinstalled; supports additional front fans (80 mm)
Front panel connectivity: 1 × USB 3.2 Gen 1 (Type-A) port
Power supply: ATX power supply compatible (not included)
Colour: Black

How to use

Install a compatible Mini-ITX or Micro ATX motherboard inside the case and secure it to the standoffs provided. Mount the ATX power supply in the designated compartment and route power cables to the motherboard and drives. Fit 3.5" and 2.5" drives into the appropriate bays and install any 5.25" device into the front bay if required. Connect the front-panel USB port and any case fan headers to the motherboard for power and control. Ensure the preinstalled rear 90 mm fan is connected and that any additional front fans are oriented for optimal airflow.

Usage recommendations

For reliable thermal performance, maintain unobstructed airflow by keeping cable routing tidy and installing at least one front intake fan if the system will host higher-heat components. Use a quality ATX power supply sized to your component needs and verify drive mounting screws are secured to prevent vibration. Regularly clean dust from fan intakes and filters to preserve cooling efficiency.
