Overview

A compact Micro-ATX mini tower with a mesh front panel and tempered glass side window. It fits full-size graphics cards and includes a 140mm rear exhaust fan.

Compact Design and Airflow

The Q300L V3 uses a mesh front panel to pull cool air directly into the chassis. A 140mm fan is pre-installed at the rear for exhaust. The tempered glass side panel provides a clear view of internal components.

Hardware Compatibility

The case accepts graphics cards up to 366mm long and CPU coolers up to 178mm tall. It supports Micro-ATX and Mini-ITX motherboards with ATX power supplies up to 200mm in length.

Cooling Flexibility

Up to six 120mm or 140mm fans can be mounted across the front, top, rear, and bottom. Dual 240mm radiators are supported at the front and top for liquid cooling setups.

Versatile Orientation and I/O

The chassis can stand vertically or lay horizontally. The I/O panel relocates to the top or bottom to match orientation. Front I/O includes one USB-C 20Gbps port, two USB-A ports, and a combo audio jack.
