why any current mainstream PC hardware can't be Hackintoshed? I read the various articles and threads, and it appears to me that the people who have done it successfully are rolling the dice on a first try, then others repeat a past success.

There are endless possible combinations of parts. I've got a shopping list from Newegg that would make a nice unit for under a grand ... but unless I repeat someone else's success, I have no idea whether it will work.

Are there any common characteristics which stand out as *cant be done*? Or a common characteristic which tilts the odds of success in a builders favor?

Thanks in advance for any ideas.
