Internal dimensions decide whether your equipment fits — size on these plus at least 20 mm of clearance per axis. Usable interior volume is lower than the theoretical L×W×H figure because of the corner radii, the seal channel and the hardware. External dimensions decide whether the case fits a pallet, a rack or a vehicle.
