Additional Comments: I'm a beginner, all advice will be appreciated. I have a hard drive and disk drive that I am reusing, I can't link to them, as they're stock parts from an emachine I bought a while back, plus I'll probably buy a graphics card later as I'm short on money at the moment, unless someone can come up with a solution.
Build I've just done, which should be close to your needs. PSU allows for adding a 2nd graphics card. Have left out hard drive and optical drive, that you already have (trust they are suitable). Put in an SSD, but you can obviously drop that, if you don't want it. PCPartPicker part list / Price breakdown by merchant / Benchmarks
