Hello,

Maybe you should take a look
HERE or THERE
These are the recommendations from tonymacx86 Blog, you will find four different Systems, depends on how much you a planing to spend for it. There are also lots of Files and HowTos for these Systems on that Site + Forum.

If you really want a System that runs OS X native >> Get a Mac.
There is always a little work with OSx86 Systems, if you are aware of that fact, and don't expect everything to run Out-Of-Box plus you are willing to spend some time getting everything to work, the Systems from tonymacx86 are a pretty good choice.

If you expect just putting in the OS X DVD and installing the System, you will not be very happy with those Systems. But once you get OS X to work on those Systems, it will work really great.
