This Original case is suitable for Raspberr pi 2 and 3 versions, there is room enough to add a dual- or single-band radio to the raspberry pi. If you want to mount an antenna, no problem, you can dril a hole in the top-plate, and mount the antenna. If for any reason you want it delivered including the hole for an antenna, please check the 'drill hole'. Antenna needed? just check the 'antenna' checkbox, and we will add it.
