Are these all water machines? There are some air-cooled versions that are
probably reasonable.

Yes, the 400 Hz would be a problem, almost as much as a cooling system (if
one went with a water machine - probably too big of a headache).

No. Around me, electricity is not very cheap - 11 cents/kWh - but running
a 50kW computer is not a financial burden if done in moderation. What
might be a burden is getting the service entrance of the house to a point
where it could handle 50kW nicely.

I suppose that is the good thing about RCS/RI - we are in a factory, and
are looking to get real 3-phase installed!
