Chieftec CS-12B-300 computercabinet mini tower sort 300 W

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.

How to use

Install an mATX motherboard into the case using the quick-release brackets to secure the board and other components quickly.

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.
