Chieftec CT-04B-OP computer case Mini Tower Black

The Chieftec CT-04B-OP Mini Tower Black is a compact PC case engineered for small-form-factor builds while maintaining effective airflow and practical drive support. Constructed from SECC steel and finished in black, the case accepts Micro ATX motherboards and offers internal mounting for 2.5" and 3.5" drives as well as external 5.25" bays. Front and rear fan support for 80 mm, 90 mm and 120 mm fan sizes enables flexible cooling configurations for quiet or higher-performance setups. With external dimensions of 180 mm (W) x 425 mm (D) x 352 mm (H) and a lightweight design, the CT-04B-OP is suitable for space-constrained desktops and office environments.

Advantages

The case combines a compact Mini Tower footprint with support for multiple fan sizes, allowing tailored airflow solutions. Its SECC steel construction provides structural rigidity while keeping overall weight low. Front-panel connectivity includes two USB 2.0 ports and two USB 3.2 Gen 1 Type-A ports for fast data transfer and peripheral compatibility. Tool-compatible drive bays for 3.5" and 5.25" devices expand storage and optical drive options without sacrificing internal space.

Suitable for

• Home and office Micro ATX computer builds
• Compact gaming or multimedia systems with limited desk space
• Systems requiring several internal hard drives and optional 5.25" devices
• Upgrades where front USB 3.2 Gen 1 connectivity is needed

How to use

Install a Micro ATX motherboard on the provided standoffs and route power and data cables through available openings to maintain airflow. Mount storage devices into the 3.5" or 2.5" positions and secure optional 5.25" devices in the front bays. Configure front and rear fans according to desired cooling performance, selecting compatible 80 mm, 90 mm or 120 mm models. Connect front-panel USB ports to the corresponding motherboard headers for immediate peripheral access. Ensure the power supply (not included) fits the case layout and cable lengths are sufficient for neat routing.

Recommendations

For balanced airflow in a compact build, install a 120 mm intake fan at the front and an 80–90 mm exhaust at the rear, and maintain clear space around intake vents. Use SSDs in 2.5" mounts for faster system responsiveness, and add 3.5" HDDs where bulk storage is required. Verify motherboard and cooler clearance before purchasing taller CPU coolers or long expansion cards.
