You know that alot of things are required and yet you are so vague about what components your computer will have?
^^I agree. Although I hate Macs (wayyy overpriced), OSX86 is a pain. It was kinda fun because when I finally got everything working I ended up by learning a few things about the os, and it got me interested into some other things. As for a guide, you can look on the InsanelyMac forums, they've got plenty of those. But it really depends on your specific hardware. You may get errors that nobody else has gotten, or you may get errors that are easily fixable.
