1. Its technically illegal to insta OSX on non Apple hardware, however since Apple doesn't use proprietary hardware anymore, techinically they are breaking their own license. When you buy OSX you get a Apple sticker so as long as you put it on your case your legit.
2. It is possible and easy to do OSX on Intel based PC if you have certain compatible parts. Your Intel motherboard is not one of those that are easily supported, and you also have to have a OSX compatible Graphics card. It will definitely not work with your onboard video.
