Retro-gaming on the Raspberry Pi is nothing new. We have already covered plenty of DIY game consoles based on this platform. This Retropie Barrel Arcade is also worth a look. It comes with everything you need to play classic games. It is running RetroPie on a Raspberry Pi 3B+.
As breadtangle explains, this arcade machine has Logitech z506 speakers, a soft power switch for the Pi on the left, and extra USB ports on the right. You can find out more here.
