Got this DELL optiplex 9010 for free and started throwing in/upgrading parts along the way. So this optiplex started out with i5-3470 cpu, no dedicated gpu, 4 gb of ram and some fishy 275W power supply. Keeping in mind that new parts cost much more than used ones I started to look for some second hand deals. This is what I have so far. Everything runs smooth as silk and temperatures under load are on the lower side. Couldn't be any more happier with this.
