The Chieftec CI-03B-OP, also known as “The Cube”, is a new and compact computer case that stands out above all with its unusual, hi-fi-inspired design. The front is deliberately designed like that of a subwoofer, which gives the enclosure a special look and makes it an eye-catcher on the desk. Despite its comparatively small size, the case offers a wide range of options for powerful desktop PCs, especially for gaming setups and multimedia applications.
- Compact design in HiFi subwoofer style (385 x 365 x 355 mm)
- Supports Mini-ITX and Mini-ATX mainboards, graphics cards up to 335 mm
- Flexible cooling options: 200 mm front fan pre-installed, space for 240 mm radiator
- Good connectivity with USB-C 3.2 Gen 2, USB 3.0 and audio connections
Compact and eye-catching with well thought-out features
The Chieftec CI-03B-OP is aimed at users who prefer a compact desktop PC without having to sacrifice important performance features. With dimensions of 385 × 365 × 355 mm, the housing is deliberately compact and therefore fits perfectly on any desk. However, it cannot accommodate standard ATX mainboards, but only supports smaller formats such as Mini-ITX and Mini-ATX. It is therefore specially designed for space-saving builds that still offer sufficient power.

A special feature is the integrated 200 mm fan at the front, which ensures an efficient and quiet supply of fresh air. At the top, there are two slots for 120 mm fans or alternatively an up to 240 mm radiator for installing a water cooling system. A 120 mm fan can also be installed at the rear. As a result, the case enables versatile cooling concepts that support both air and water cooling and provide optimum temperature control for important hardware components.
Flexibility in hardware and connection options
Despite the compact design, a powerful system can be realized: Graphics cards up to 335 mm in length can easily be accommodated, and there is also space for CPU coolers up to 160 mm in height. Two 3.5-inch and two 2.5-inch bays are available for storage devices, allowing larger storage capacities for larger amounts of software or media archives.
The case is also well equipped in terms of connectivity: there is a modern USB 3.2 Gen 2 Type-C port and two USB 3.0 ports at the front. There are also separate sockets for headphones or speakers and for a microphone, which is ideal for gaming or video chats.
Installation is facilitated by a practical folding mechanism that allows quick access to the interior – an advantage for maintenance or hardware upgrades.
Conclusion
The Chieftec CI-03B-OP is a compact, stylish case that stands out with its subwoofer look and impresses with its practical features. It is perfect for users who want to build a powerful gaming or multimedia system in a small space. Support for mini-ITX and mini-ATX mainboards, extensive cooling options with fans and radiators as well as modern connection ports make the case a versatile solution. The Cube is available from around 70 euros, offering an attractive price-performance ratio for compact desktop PCs.
