I have my retropie up and running on my Pi 3 and my controllers working. I bought a small cabinet and buttons and Ill eventually install everything into the cabinet and get the 1 and 2 player buttons and joysticks set up along with a monitor. My question is, how do you guys power everything? Do you use a power strip and plug the monitor and pie into it inside the cabinet? Seems kind of messy. I can solder but I know little about electronics. What is the best way to minimize plugs? Use an ATX power supply and run the pie and TV off that? (Is that even possible?) Any suggestions and instructions would be awesome. Thanks Guys!
Also, is there a way to create a switch or button that turns everything off and on together while also safely shutting down the emulator as opposed to just a hard unplug?
