MasterBox 600 ATX Mid-Tower Case

The Cooler Master MasterBox 600 is a black mid-tower chassis built for ATX motherboards. It provides a standard enclosure for desktop computer assembly with a clean, dark exterior.

Suits ATX builders; not for larger boards

This case fits builders planning a standard ATX system who want a mid-tower footprint. It is not for users who need support for Extended ATX or larger motherboard form factors.

ATX mid-tower form factor

The defining specification is the ATX mid-tower form factor, which determines the motherboard sizes and internal volume available for components. This single constraint decides whether the chassis matches the build plan.
