Overview
The Cooler Master MasterBox Q300L Retro is a MicroATX Mini Tower with room for Mini-ITX motherboards. A acrylic side panel shows off the build. GPU clearance reaches 400mm — room for full triple-fan flagship cards — with 170mm of air-cooler headroom. It comes with 2 fans pre-installed and mounts up to 6.
In the mid-range bracket, prioritize GPU and cooler clearance — small cases punish part-picking mistakes. Expect to pay around $61.99, which lands it among mid-range options. PlanMyPC's builder flags compatibility problems automatically and tracks the latest PC case deals from multiple stores.
