The installation process with Q300L is one which requires little effort thanks to the helpful design implementations that Cooler Master has employed. We were surprised by how much high-end kit this small, compact chassis can house and were even more impressed by how easy the cable management was to keep under control. The Q300L handled our Micro ATX test system with ease!


Installing such items as storage drives is very straightforward – for 2.5” drives, rubber plugs and screws just need attaching to the underside and then the drive just slides into the mounting holes on the motherboard tray.
