I am running OSx on my box.
Still is a little bit choppy, but hell it runs. Right now, I am typing this on an OSxPC. IT is cool, but once I get the ATI drivers finalized, it all over. No more windoze for me. I used the "deadmoo" imgae to get mine all setup, and I had little to no problems getting it to work.
HAHAHA, If i get the ATI drivers loaded in, I think I may be trading the OSxPC for the shiny new G% my parents have.
