I WOULD RECOMMEND GETTING LIKE A GOOD BRANDED PSU LIKE A 500W CORSAIR, OCZ, OR PC POWER & COOLING

That is a pretty..uh...vintage CPU, i would try to get at least a core 2 duo.Roggirek

The E6300 and other processors currently-branded "Pentium Dual-cores" are Core 2 Duos. The changed the name to differentiate them from the higher-end CPUs (E7xxx and E8xxx series).
