I built a Hackintosh based on the guide I found here about 6 years ago. I didn't have any experience building PCs so I definitely learned a lot! With a few upgrades along the way, it's been my main editing machine since then. The whole scene has evolved so much since those days and thanks to things like Clover Bootloader hackintoshing is easier now, than ever. Once you have everything set up it functions just like a regular mac. Updates can even be applied normally without breaking anything!
I'm glad to see you guys updated your guide because I could have never afforded the Mac equivalent of the Hackintosh I built years ago and I'm sure there are others in the same boat now.
Potential hackintoshers beware! - Although things are much simpler than before, you need to have a strong DIY attitude when pursuing this. It definitely pays off in the end though! This guide tends to glance over the software end which is definitely the most difficult part. I recommend checking out "Golden Builds" on the TonyMac site since those are proven hardware configurations with detailed documentation on the software end.
