Overview
The Cooler Master MasterBox Q300L is a MicroATX Mini Tower with room for Mini-ITX motherboards. A acrylic side panel shows off the build. GPU clearance tops out at 400mm — room for full triple-fan flagship cards — with 170mm of air-cooler headroom. It ships with 2 fans pre-installed and mounts up to 6.
In the budget bracket, prioritize GPU and cooler clearance — small cases punish part-picking mistakes. Its $39.99 price tag places it squarely in budget territory.
