Building my own Computer

Hey guys, I've been an avid fan of Apple for years. However, I want to start playing some PC games a bit more than I have in the past. So this is a bit off subject but I've always trusted your opinions.

I was wondering if someone new of a site that I could go to learn about building my own PC. I actually know how to build the computer myself. I'm just lacking sufficient knowledge on how to distinguish one part from another as being good. So I was hoping to find a similar site to this, but for PC users instead. If someone could help me out, I would appreciate it.

Thanks

 

thx
