Blog post leaves out an important point: is it easy to get macOS running on that particular model? edit: The mini hasn't competed on a purely specs/price level since, perhaps, its first year or two of existence. There have long been better, similarly sized options if you don't care about OS X.
According to the Lifehacker article on building a Hackintosh, the process is a lot less fiddly than it used to be, and a lot more hardware is now supported. Other guides suggest that the NUC is mostly supported, bar a few issues (e.g. on-board mic doesn't work, not the infra-red sensor). However, even if you have a totally legit paid-up copy of OS-X, it's only licensed for installing on Apple hardware.
For most of the hackintosh ports onto the NUC or NUC-style hardware, the onboard Bluetooth/WiFi is usually not supported because there are no OS X drivers for the integrated chipset used. This is kind of a deal-breaker for me. The process of applying new OS revisions is also painful. I guess the hackintosh process is pretty straightforward on certain models of full-size motherboards, but I haven't seen a fully functioning SFF impementation. If there was one, I would get such a box.
