Cooler Master unveils $45 Q300L V3 micro‑ATX PC case

Cooler Master has released the Q300L V3, a $45 micro‑ATX chassis aimed at budget‑conscious builders. The 15.2‑inch square, 9‑inch deep case is made from 0.80 mm steel and can be used in either vertical or horizontal orientation. Its standout feature is a modular front panel that can be repositioned and includes a USB 3.2 Gen 2×2 Type‑C port, two USB 3.2 Gen 1 Type‑A ports and a headset combo jack.

The rear panel houses a 140 mm exhaust fan (supporting 120 mm replacements) and a folded‑out card‑holder tab, while the power‑supply mount is designed to clear the bottom‑corner radius. The design offers flexibility for component placement and an affordable entry point for high‑speed connectivity without the typical $100 price tag of comparable cases.
