The CHIEFTEC CS-12B-300 is a compact Mini Tower case designed for mATX and Mini-ITX motherboards. Its slim chassis can be positioned either vertically or horizontally, suiting a variety of home and office environments. The case is constructed from 0.6 mm SGCC steel and includes a 300W TFX power supply with an 80 PLUS Bronze efficiency rating. This pre-installed PSU simplifies the build process for systems with specific, low-profile power requirements. The front panel provides access to two USB 3.2 Gen 1 ports, two USB 2.0 ports, and standard audio jacks.
Internally, the layout is optimized for space efficiency with a maximum CPU cooler height of 85 mm. It accommodates up to four half-height PCI expansion cards, a specific requirement for low-profile components. For storage, the chassis provides one 3.5-inch bay, one 2.5-inch bay, and an external 5.25-inch bay for optical drives or other accessories. Cooling is handled by a single pre-installed 80 mm fan at the front, and the design incorporates quick-release bracket technology to facilitate easier component installation.
