Overview
The Cooler Master MasterBox MB400L is a MicroATX Mini Tower with room for Mini-ITX motherboards. GPU clearance reaches 400mm — room for full triple-fan flagship cards — with 170mm of air-cooler headroom. A tempered glass side panel shows off the build. It ships 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. Its $83.08 price tag places it squarely in mid-range territory.
