And if it gets popular, the price of old Xeon workstations will go through the roof, just like old stereos did. Used to be able to get an old Marantz 2220B for $100 on the bay. Now they are unobtainium or $850, as an example.

I think the same thing happened to old Sun workstations. We used to reuse them a LOT. Could get an ultra 2 decked out for like $200. Now, $800-$1000 with less CPU and ram than a few years back. Could be supply and demand, but it seems to happen a lot. People go "hey, that stuff was great, lets use it again" and the price skyrockets, then the people all go "hey, that old stuffs too expensive".
