That much isnt nesscary, this isnt an SLI'ED PC with phasechange
Thermaltake td-420ad is cheap (30$) and will do you fine.
Also like the other people said, look for a graphics card, 6600GT is a good suggestions and will be able to play anything right now, and a 9550 128meg if your really strapped for cash.
