Me too, my 6 core machine is running Zwift and Fulgaz permanently in a cycling paincave room connected to a 55” 4K HDR TV.
It runs Monterey and just works. Dreading the day the software support moves on from Monterey, but can run Windows. I got that machine second hand only for its original dual CPU tray (to put in my good one), then figured why not keep it working too.
