The Chieftec UB-03B-OP is a mini-tower case designed for systems built around the Micro ATX motherboard standard. Its construction consists of 0.5mm SGCC steel, providing a functional chassis suitable for home or office environments. The case features solid, opaque side panels, maintaining a clean and understated appearance. It is configured to accept standard ATX power supply units, offering flexibility in component selection within its compact footprint.
Internally, the layout supports up to three 3.5-inch drives and one 2.5-inch drive, accommodating common storage configurations. The cooling system is pre-configured with a single 120mm front intake fan and an 80mm rear exhaust fan to establish an airflow path. Component compatibility is defined by a maximum CPU cooler height of 145mm, a key metric for builders when selecting third-party air coolers. This design focuses on core functionality for essential builds.
The front panel provides direct access to relevant connectivity, including two USB 3.2 Gen 1 Type-A ports and separate microphone and audio-out jacks. A notable addition is the integrated card reader, which allows for media transfers without external adapters. For physical security, the chassis incorporates a Kensington lock slot, allowing the system to be secured in place in a public or shared setting.
