Cooler Master announces Q300L V3 and modular Qube 340 cases

Cooler Master has announced the Q300L V3, the next generation of its compact microATX case, alongside a modular version called the Qube 340.

The updated Q300L chassis supports Mini-ITX and mATX motherboards within a small desktop footprint. It has room for graphics cards up to 366mm long, CPU coolers up to 178mm tall, and up to six cooling fans in total. Airflow potential is boosted by enlarged front-panel perforations and compatibility with a 140mm rear exhaust fan.

Structural improvements over the V2 include reinforced fan mounts, an upgraded motherboard tray, and a tempered glass side panel. For connectivity, the refreshed front I/O panel houses three USB 3.2 Gen 2×2 Type-C ports, dual USB 3.2 Gen 1 Type-A ports, and a combo audio jack.

Builders can opt for this standard layout, but the company is also offering the modular Qube 340 alternative. This version shares the same core mATX foundation but introduces optional handles, support for vertical or horizontal system orientations, and flexible front I/O placement. It additionally includes front-mounting support for compatible 3D-printable accessories.

KitGuru says: The original Q300L was a popular budget option, and adding modern USB-C connectivity alongside other improvements sweetens the deal.
