If you work carefully, you will not have to repair the sheetrock you will have cut out as the opening will be covered by your display case or wall cabinet.
Metal studs will support vertical loads. They will not support a heavy load whose center of gravity is away from the vertical plane of the wall i.e. a wall cabinet filled with china and glassware.

People tend not to understand. The wall board screws that people seem to use for everything are thin. Any screw has limited holding power into end grain. Unlikely anyone will do it but the solution is to drill a hole across the grain close to the end where the screw will be in it and glue in a dowel. The screws will hold better and it prevents the wood from splitting along the grain-it's weakest point.
