I am thinking about adding a Mac mini to sit beside an Apple TV 4K so as to support video conferencing using Zoom and a Logitech Pro (aka Brio) 4k webcam. I thought I'd buy a used Mac mini from e-bay since the computer will do almost nothing else. (I already have a recent MacBook Pro for everyday workloads.) So what is the oldest / least expensive model I can buy that will still work nicely to handle live 4k video and audio for a 55 inch 4k TV? I'd like something that will work without weird hacks, won't be laggy, etc. but the computer will probably do nothing else and I don't intend to do any video editing, just live streaming.
Suggestions?
