## Summary description

The Chieftec CS-12B-300 is a compact Mini Tower computer case designed for efficient cooling and easy installation. It features a sleek black design, a 300 W power supply, and supports both 2.5" and 3.5" HDD sizes. With one 80 mm front fan installed, it ensures optimal airflow. Dimensions are 102 mm in width, 356 mm in depth, and 338 mm in height, making it a perfect choice for space-constrained setups.

## Long description

The CS-12B-300 is a compact, multifunctional micro-ATX chassis designed for both horizontal and vertical placement. Its space-efficient design supports a full mATX motherboard while maintaining a clean external appearance. The case ships with a low-noise TFX power supply model GPF-300P, providing integrated power for typical small-form-factor builds.
Advantages
The chassis features quick-release bracket technology that simplifies component installation and maintenance. With four expansion slots it supports up to four half-height PCI cards, enabling flexible expansion options. Bundling with the GPF-300P TFX power supply reduces the need to source a separate PSU and helps ensure compatibility in compact builds.
Key specifications
 Form factor: micro-ATX (mATX) compatible
 Orientation: supports horizontal and vertical placement
 Expansion slots: 4 (supports up to 4 half-height PCI cards)
 Included power supply: TFX GPF-300P, low-noise, 300 W
 Drive bays and internal layout: compact, optimized for small-form-factor components
How to use
Install an mATX motherboard into the case using the quick-release brackets to secure the board and other components quickly. Fit expansion cards into the available half-height slots and connect power from the included GPF-300P TFX supply. Mount storage and cooling components according to the internal layout, ensuring cables are routed to maintain airflow and access to ports whether the chassis is positioned horizontally or vertically.
Recommendations
The case is suited for compact workstation or home systems where space is limited; verify compatibility of your cooling solution and full-length expansion cards before assembly and use a low-profile CPU cooler if needed.
