So long story short, no matter what i tried it wouldnt work.. After trying many things, my computer wouldnt turn on anymore, motherboard died.. Not sure if its an issue caused by trying to install OSX or what, but ended up swapping out the motherboard for a P8P67 Pro v3.1 and i've got 10.6 installed with only two problems.

First Problem: Cant get my WNDA3100v2 to work, to get internet i have to tether using bluetooth through my phone.
Second Problem: It wont boot by itself. I used Andy's Boot CD and his guide, which included installing the P8P67 Pro package which would allow you to boot, but it didnt work. I have to use the boot disc every time.

Any ideas on problem 2?
