Searching for parts

At this moment I'm very busy with preparing for the conference in Amsterdam and I feel like i need a few days AFK. So I'm looking for parts in my inventory to build the arcade. Already found a screen, pi4, amplifier, joysticks and a nice mix up for the buttons. Yes that's correct, it will be a two player co-op arcade... Want to keep it as simple as I can so people can eventually build their own cabinet.
