One comment mentions the possibility of using old ARM tablets in a hackintosh build, but this seems to run against one of the two reasons for using hackintosh over Mac directly - performance. Cost would definitely be a benefit, but I'm less convinced of the value here.
I imagine though that this is literally the end of the hackintosh entirely. With control over basically all the hardware, there are no more workarounds or backward compatibility aspects. Hell, even external GPU aren't supported as-yet.
