I find myself craving an original PC from time to time.

Yeah, big iron! I am interested but lack the space, so I watch others with great interest.

I did get really into Sgi machines, but those are a newer breed. They do have that big iron feel. At one point I had quite a set, Origin server, Indy machines, an O2... purged it all in the early 10's and went small, embedded after that.
