New PC build

Hey guys, it’s been a while. I’ve taken a break from Sharenator because of all the BS I saw here, and just didn’t think it was right. So, here I come to ask you all for advice:

I want to build myself a PC for the experience of building my own computer, and possibly a Hackintosh with OSX 10.6.8 (love the OS, hate the price). My budget is loosely around $600, or whatever will get me close to the specs of this Mac Mini, with the CPU and GPU being my bottom line, maybe a quad-core i5 or i7, and enough of a GPU to get by on gaming. As far as a starting point, I already have a microATX case available, and I get that I may need to start from scratch with a bigger MoBo.

If this project turns out fruitful, I was hoping to use the machine mostly for recording/mastering my music and playing the odd PC game here and there. Any advice that you guys may have about the hardware for me to choose, how to go about it, etc., I’m open.

Thanks, best wishes.
