Just like to say that I was able to install OSX with kakewalk on Z68-UD3H-B3 EVGA 470 GTX i5 2500K 16gb corsair vengeance 250gb 7200 RPM drive (connected into sata 2) - I was unaware that os x has problems w/ sata 3 but that was my only problem and changing the connection fixed it. sony optiarc cd drive
After installation I used multibeast to install kexts for audio and networking
Problems - I have issues booting up but after 1 or 2 tries it gets it.
