## Long description

REFRESH YOUR STYLE. The Q300L V2 compact PC case combines a modern perforated design with a magnetic dust filter and an edge-to-edge tempered glass side panel. It supports a USB 3.2 Gen 2x2 Type-C port on the I/O panel for data transfer up to 20 Gbps and offers flexible fan and radiator mounting options to maintain effective cooling. The case also provides 28 mm of space behind the motherboard tray for cable routing and supports both vertical and horizontal positioning.
Advantages
The redesigned magnetic dust filter improves airflow while reducing dust entry through a patterned design. Perforated front, top and bottom panels ensure excellent thermal performance. The tempered glass side panel (4 mm thick) displays internal components and is secured with thumbscrews for easy installation. Multiple mounting locations accommodate fans and radiators, and the case accepts a USB 3.2 Gen 2x2 Type-C port for high-speed connectivity.
