That board seems to have pretty rave reviews from the Hackintosh community, which is why I started checking it out. Looks fairly future proof, but yeah, it might be a better idea to hold out a bit longer and see what Mavericks h/ware requirements are. Can't imagine it being too different from ML though. I never thought I'd get sucked in to trying this until I get it right, haha !
I'm actually missing my mountain lion setup, ill dabble again when Mavericks comes out.
