Honestly, before this, I haven't built a serious Hacintosh in probably about 9 years (last time I did chameleon was still the preferred bootloader), I did rebuild a a Xeon 5450 Frankenbox like 2 years ago; I just used unibeast to get that installing (El Capitian) and them did a vanilla clover and configured it. This was a little more convoluted as the Mobo is one of those Chinese Jingsha X79 mobo's (though I would say its one of the better designed ones), which documentation is NIL and they don't really have consistency in software (stuff like bios) or even chipsets (recovered chipsets). So I kinda poked around; they are very popular in the Russian PC enthusiast realm, and I gleaned some info from them on what DSDT patches, bootloader options (and values) and kexts they were seeing success with, I ripped a copy of the DSDT to text and started tinkering. Ultimately I used the mac installers built in bin to create a boot media and then used clover.
