I'm attempting to build a PC with a budget of around 600 dollars. The only piece I have right now is the case, an Antec 900. I would appreciate any help that you could give me. This is what I was thinking GPU - HD 5770 CPU - AMD Phenon II X4 Black Edition DVD Drive - Lite On DVD Drive I'm not sure what size power supply is best suited for this build. Also not sure what mobo, HDD, or Ram I should be getting.
