Cooler Master rolls out the Q300L V3, a compact microATX chassis aimed at first‑time builders and budget gamers. The new case keeps the familiar footprint while adding a tempered glass side panel and reinforced fan mounts. It supports Mini‑ITX and microATX boards, 178 mm coolers, 366 mm GPUs, and up to six fans and a new airflow design that boosts intake performance.

Airflow takes center stage. Enlarged front‑panel perforations raise intake, while a 140 mm rear exhaust fan slot offers cooling flexibility. The chassis now tolerates taller CPUs and larger graphics cards, giving builders room to fit higher‑performance components without sacrificing the small footprint that made the Q300L line popular among compact builds for gaming and integration projects today and tomorrow in the.

Front I/O updates include three USB 3.2 Gen 2x2 Type‑C ports, two USB 3.2 Gen 1 Type‑A jacks, and a combo audio jack, giving users speedy connectivity without clutter. Cooler Master also offers the QUBE 340 modular companion, adding handles, vertical/horizontal orientation, and flexible I/O placement. Together, the two models supply builders with a modern, adaptable microATX platform that feels solid and refined for today.
