I just bought a used Dell PowerEdge 2950 II with six PERC 5i SAS SATA drives at 73GB each (Seagate Cheetah 15k.5, Firmware S527). I plan to install Ubuntu Server on it. Since this will not be a "production" machine, just for experimenting, can I jerk five of those six drives and replace the one with a suitable 1TB drive? If so, what brand/model/spec 1TB could I use? Also, can I jerk out one of the two power supplies? ... All of this before installing U13.04 Server? Again, this is not meant to be for anything but learning and experimenting.
