A DS10 would be a fair choice, though the system is limited in to 2 GB
main memory and just
three internal disks. It has one EV6 cpu that runs at 466 MHz. I don't
know whether faster cpu's
are supported. A DS10 is not noisy and is easy on the electricity
bill. But a DS10 still has some value.
Older Alpha's, like the AlphaServer models 800 and 1200 run slower
(EV5 cpu(s) at 333, 400 and 500 MHz).
You might get these cheap or for free.
Two weeks ago I was given a DS10 and a DS20E with 4 GB, 5 internal
disks and two EV67 667 MHz cpu's. Now that's a
real hobbyist system! The downsize is that it runs fairly hot (so runs
up quite an electricity bill).
