I still have these in service at $ork (4 in service, 4 spares, + a few parts
boxes).

It will not always stay powered on for more than a few seconds. I have

Power supply does sound like the problem - as far as I remember, it was not
an uncommon issue.

I rarely see parts for these.  The power supplies are still available from
HP (as far as I know), but probably cost more than a whole spare box from an
HP reseller (we've been paying around $400-600 for these workstations with a
reasonable configuration in new or as new condition).  Some potential
sources for parts or spare box include:
