Using a Picade with a PC as an external monitor and USB controller


Hi Guys. I am very new to Rasp Pi’s and I will soon be getting one of your new Picade’s with the intention of pairing with a Pi 3B+. However I was thinking ahead to the future that I may want to use the actual cabinet as an external monitor for my gaming PC which i already have setup with emulation software and a front end. What would I need to be able to connect it up to my PC. I have a rough idea but want an experts opinion. Many Thanks Ads
