Such a throw back, I built a hackintosh back in x86 days and had it mostly working for a year, but of course tried to apply an update (10.08 I think?) and it blew up.
Ended up selling the hardware to some guy who insisted he would get it working and I am sure it was possible, but I pretty much switched to using Mac after that as I loved the dev experience.
I had OSX running on an old school flip-screen HP tablet/laptop combo with touchscreen support. It was bulky but cool to use as a drawing tablet in the pre-iPad days. You did need to have a paper clip inserted into two holes of the VGA port for it to work, and I don't think it handled sleep very well. But still a fun project.
I ran OS X on a Dell mini 9 for two years while travelling. Other than sleep, it was excellent.
Things got much better with OpenCore. Sometimes you had to tweak a few extra settings, but generally you could update it just like a regular Mac. Point updates worked especially well.
