Part of the answer depends on where the system is currently located. If it's in a standard BA213 cabinet it wouldn't be cheap to ship and would be more appealing to someone who could acquire it locally. The cost of shipping alone might not be too far from the value most hobbyists would place on the system itself.
It also depends on the system configuration. How much RAM it has, does it include working DSSI drives, does it include additional controllers especially SCSI controllers, what the cosmetic condition is, lots of these systems turn up missing body panels from the cabinet.
Off the top of my head I'll throw out a starting number of $200. If I could buy one locally for less than that I might have some interest. If I was trying to sell one locally I would hope to get more than that. Again the exact system configuration would change the value.
I'm sure other people here have differing opinions on the current market value.
