I programmed a smart voice assistant that is like Jarvis from Iron man. I still needed a housing for the technology (speakers, display and a Raspberry Pi). The holes at the back are for the speakers. The slot at the front is for a USB hub. 
If you want to recreate the project, here are the links for the technology I used:
