The machine advertised is a Z440. I received a Z420. The cpu listed is the Xeon E5-1630. What I received is a 1603. The 1603 is almost half the benchmark of what was advertised. Also the graphics card is only an ATI FirePro 1gb. The machine shipped from Sunset Micro was shipped late as well. I bought this computer to run a plex server and imeaditly ended up upgrading parts to even be half decent. While it is currently capable of running the server, it's only about half of what it should be.
