Features

QUBE 340 White

Handle-equipped configuration with modular accessory support.

QUBE Family Modular DNA
Inspired by the modular philosophy of the QUBE family, QUBE 340 introduces flexible customization options for small but powerful builds. Optional handles, flexible front I/O placement, and front panel mounting points for 3D-printed accessories allow users to personalize both aesthetics and functionality. The chassis also supports vertical or horizontal placement, continuing the adaptable design approach seen in QUBE 540 and Q300L.

Thermal Performance Upgrade
Designed under Cooler Masters Thermal Excellence philosophy, QUBE 340 enhances cooling capability with larger front panel perforations for improved airflow intake, support for up to 6 fans, and an upgraded 140 mm rear exhaust configuration. Increased CPU air cooler clearance up to 178 mm further enables strong air-cooling performance for mainstream high-TDP systems.

Improved Structure
An improved motherboard tray and optimized fan mounting layout enhance chassis stability, while enlarged front panel perforations improve airflow intake efficiency for better cooling performance.

Easy Build Experience
Optimized internal layout with 30 mm cable routing space enables clean cable management and an intuitive building process for both first-time builders and system integrators.

Hardware Compatibility
Supports GPUs up to 366 mm (without front fan installed) and accommodates mainstream high-TDP air coolers, ensuring strong hardware compatibility within a small form factor.
