This is really helpful, thank you. What you say puts some form and empirical evidence to my concerns about Hackintosh. I guess my gut had it right this time, which is unusual. So you can brick your fancy new homemade, warranty-less PC!
Anyway maybe one day I'll do it for fun on a crappy laptop I get off Craigslist. Sounds like this pays off most when it's a low-risk effort.
