Hey guys I need help putting together a budget machine for under $500 not including tax/shipping. This build will be used primarily for heavy gaming, home theater use, and mild media converting. I want to have this build ready before 1-10-10. The parts I already have a video card, hard drive, and power supply I will be reusing. I do not plan on using more than 1 video card at any time and if possible I would kinda like a SFF build but if not it's cool too. Sorry I've been away from computers for a while so I don't really know which parts are the most bang for your buck right now.
