My friend has some sort of dell, he put an FX5700 in it (i think) because all he had was PCI. Then he added another DVD burner and a 250gb HDD. Needless to say, it didnt run too well. Hes now using my old Xion 480W psu (total P.O.S. psu

) because the one that came in it was only 250W. He was also trying to upgrade the cpu to something better but from what he says you cant buy many in that configuration. Anything better needs a new mobo (this is micro-atx) which needs a bigger case and it goes on.
So i would say no, i dont like dells.
