The CHIEFTEC The Cube is a new compact micro-ATX chassis designed with a distinct Hi-Fi-inspired aesthetic, blending elements of modern furniture craftsmanship with practical PC-building usability. Its minimalist styling is paired with an innovative fold-open structure, allowing builders to access internal components easily despite the enclosures small footprint.
A large 200mm PWM fan with an HDB bearing comes pre-installed at the front, providing strong airflow at low noise levels. Despite its compact form, The Cube supports a 240mm radiator, full-size ATX power supplies up to 160mm in length, CPU coolers up to 160mm tall, and graphics cards up to 335mm long, making it suitable for performance-oriented small-form-factor builds.
