I'm pretty sure there are a lot of people on this thread that would be more than happy to build their own Mac system IF macOS was truly install-and-go portable within some reasonable range of hardware options. Hackintosh doesn't cut it for many of us as we want to use our computers, not continually tweak them to get them to work/upgrade properly. With the T2 chip becoming more ubiquitous on Mac systems I think we're seeing the likelihood of running macOS on non-Apple hardware fading into nothingness, even in a Hackintosh setting. If you want to use macOS, become resigned to Apple's hardware choices for you. If you cannot do this, it's time to bail out and go back to Windows or Linux. This is certainly becoming a decision point for me.
