I am making my first arcade cabinet build and am looking at launchbox for my front end. I plan on putting systems on it up to ps2. I am going to make a 2 player cabinet with 6 buttons each, 2 spinners, and a trackball. Does this sound like enough buttons? Also, for the pc build I am looking at an i3 10100, 16GB Memory, 1 TB SSD HD, 550W power supply, Gigabyte B460 HD3 ATX LGA1200 Motherboard. Currently I'm either going to use the onboard video or see if I can get a graphics card for a decent price as they are all really high right now. If anyone has any suggestions or if something doesn't look right, please let me know.
