Cooler Master launches QUBE 340 microATX case with top-mounted handle
Cooler Master introduces the QUBE 340, a compact microATX PC case designed with portability in mind. The standout feature is a built-in carrying handle on the top panel, allowing users to easily transport their build without needing external bags or straps. Available in black and white, this mini-tower chassis supports both vertical and horizontal mounting orientations, making it versatile for different desk setups.
The QUBE 340 is engineered for efficient airflow with enlarged ventilation holes on the front panel to improve cooling performance. It features a tempered glass side panel for visual appeal while maintaining structural integrity. The case supports up to four expansion slots and includes drive bays for two 2.5-inch drives, one 3.5-inch drive, and one shared bay.

Cooling options are flexible, with fan support on the top (two 120mm/140mm fans), front (two 120mm/140mm fans), bottom (one 120mm/140mm fan), and rear (one 120mm/140mm fan). Radiator support includes up to 240mm on the top and front, and 120mm on the rear. The case can accommodate graphics cards up to 366mm in length (without front fans) and CPU coolers up to 178mm in height.

Power supply compatibility varies based on fan configuration: with a bottom fan installed, ATX power supplies up to 140mm deep are supported; without a bottom fan, ATX units up to 200mm can fit. The chassis measures approximately 230mm wide, 429.4mm tall, and 386.1mm deep (including protrusions), with a weight of around 5.06kg.

Additional features include an I/O panel that can be mounted in either the upper or lower position to suit user preference. The front panel also includes a headphone holder and mounting points for custom accessories, such as those created with a 3D printer. Retail pricing is set at 7,480 yen (approx. $50 USD) in Japan.

The QUBE 340 is available now from retailers like Tsukumo Computer Main Store and online platforms including Amazon and Rakuten. It represents Cooler Master's continued focus on compact, functional designs that balance aesthetics with practical usability for enthusiasts building smaller form factor systems.
