I think you should be able to find old Alpha systems for pretty cheap,
as long as you avoid ones that come with an OSF/1 license... and avoid
the crooks who try to make out that a prehistoric 166-MHz Alpha (or
whatever) is "fast".
For instance here is (part of) an advertisement for Multia/UDBs I just saw:

I don't know if the M/B is an EB66 variant or not... If so perhaps
you could rip it out and put the other bits in your spare parts heap.
A good place to read some info on low-end hardware is:
