I got a Late 2005 G5 with a 23" Apple Cinema Display for free from my office and have been looking into my options for what to do with it, but the limitations of the PPC support make me think that money I put into it would be wasted. It's a shame as I am aware that it is a powerful Mac.

So I am considering ripping all the parts out and re-fashioning it as a hackint0sh.

If I do this, will I still be able to use the Apple Cinema Display?

Also, where is the best list of best compatible parts?

I have heard that it can take a lot of work getting all the drivers working correctly.

Finally, as being as this is a new build, I would like to create it with Mountain Lion as the OS for it.
