I replaced our 30 inch microwave a couple years ago with a standard residential microwave I purchased at BestBuy, and other than drilling a couple new holes in the cabinet and installing the new mounting plate on the wall, the installation went fine. The cu ft measurement is strictly how they are designed inside, and the new unit we installed actually has more room inside than the old one. The original unit was a microwave/convection oven and we went with a microwave only unit and it has more power than the combination oven had.
