I know what a pizza box and a lunch box[1] are especially since I used to run OpenBSD on a Sun lunch box, but when if ever did Windows run on a lunch box style enclosure, or a Bus Expansion Chassis, or a Peripheral Chassis? Is this an example of exceptional enthusiasm to detail on the part of the engineers?
