How do you hang cabinets on metal studs -- need to install base and wall cabinets in an office that has metal stud walls and a drop ceiling?

The correct way is to install a 2x 6 backer plate between the studs where the cabinets are to be hung. If there is not one there you can tear out the drywall and install one. However the base cabinets can be attached using metal drywall screws or lag bolts. Since the countertop will put weight on these they really wont go anywhere, the wall cabinets are the main concern. you can try to use metal stud screws and lag bolts on them as well.
