Would I be able to run OSX and build a hackintosh with this mobo?

Is it only this board you want? EVGA motherboards are some of the hardest to Hackintosh properly. My personal suggestion for an mITX board would be something from the Asus ROG series. Asus boards are not OOB compatible, but modified DSDT files are available everywhere, and Hackintoshing guides everywhere.

Take a peek at this one. Hackintosh compatible, guides everywhere to suit your needs, in the same price range as the other one, and has a killer colour scheme!
Cheers man
