500 is his absolute max? I can get pretty close, but getting under that budget with a OS is pretty difficult. It also doesn't help that newegg gone and broke their price listings atm. I could very likely get this under budget with a FM2 system. Going to try for that in a minute.

Total price - $545 everything has free shipping. Going to try something else next to see if I can get it under budget. *edit2* I could get the FM2 build at budget but I doubt it was worth the performance decrease, so I won't be adding it, but I'll be trying to get this current build under budget.
