Compact Micro-ATX Tower
The Cooler Master MasterBox Q300L is a Micro-ATX tower that also fits Mini-ITX boards. It has a steel and plastic body finished in black with an edge-to-edge acrylic side panel. The modular I/O panel can be placed in six positions on either side and the chassis works in vertical or horizontal orientation. Two USB 3.0 ports and two audio jacks sit on the panel. There is one internal 3.5 inch bay and two 2.5 inch bays for storage.
Magnetic Filters and Airflow
Patterned magnetic dust filters cover the bottom intake and the perforated front, top and bottom panels promote high air performance. A single 120mm fan comes pre-installed at the rear. You can add two 120mm or two 140mm fans at the front, two 120mm fans at the top and one 120mm fan at the bottom. The power supply mounts at the bottom and the case depth accepts a standard ATX unit.
Radiator Support and Cable Space
The front supports up to a 240mm radiator while the rear takes a 120mm radiator or fan and the top accepts two 120mm fans. Behind the motherboard tray there is 28mm of routing space for clean cable management. Four expansion slots are available for add-in cards. No hot-swap bays are included. The open perforated design aims to sustain thermal performance during extended workloads.

Soalan tentang produk ini
How do I install the modular I/O panel and which orientation mistake should I avoid?
The I/O panel mounts in six positions — front, top or bottom on either side — so choose the location before securing the motherboard; the common error is fixing it after the board is in, which blocks access to the screws.
What maintenance will the magnetic dust filters need over time?
The front, top and bottom magnetic filters lift off without tools; rinse them with water, dry fully, and snap them back — no replacement parts are required.
What thermal limit appears first when the system runs sustained loads?
With only one 120 mm rear fan pre-installed, exhaust capacity is the first bottleneck; adding front intake fans or a 240 mm radiator shifts the limit to the top dual-120 mm exhaust.
