Apple views itself as a HARDWARE company first, so I doubt you'll be able to (easily, without a hacked version) install OSX on a non-apple machine...
Besides, the new machines will be comparably priced, why not enjoy the full experience?
A great UI AND beautiful industrial design...
I like to build my own and the install information is all over the internet. I half understand how to install OS X on a non-apple machine... I'm not in a hurry. Perhaps in 6 months I'll get a Sempron or Celeron that's compatible with hacked OS X. I don't have such a setup as of now
If it will run on one of the new T6100 Nvidia nforce motherboards then I'm definitely going to do it
