So been meaning to do this for awhile and it took a pandemic to get my moving on this project. I started building a Retro Arcade cabient. Using a raspberry pi running retropie as the os. It is very easy to use, has a ton of emulators built-in and a nice themable interface that can be used with a joystick.
The cabinet I found on Etsy its pre-cut MDF that you just need to put together, paint and decorate as you see fit.
Controls and Monitor I got off Amazon
Audio I got this little 2ch amp
and just some cheap 4" speakers
Current Status: I have it built and primed. Trying to decide on some vinyl and paint designs that I want to do. Also waiting on some mount screws for the monitor.
