I built a hackintosh 2 years ago. It's been fantastic and required very little time to keep updated and running smoothly.

tonymacx86 is the go to place for checking on hardware compatibility for the most part. insanelymac tends to be more technical, it's where a lot of devs that make it all work hang out. You likely won't need insanelymac unless you are trying to get some poorly supported hardware working.

I should have noted in my previous comment but I purposely chose hardware for my build that I knew worked well. Things can get complicated if you are trying to make any random hardware work, although even that is much better than it used to be.
