there are also siemens machines like the RM200 which are 'nice' -- but 
IIRC aren't supported (yet). to make this clearer i'd ask on the 
port-sgimips or similar mailing list...

sgis -- i own a lot of sgi machines :) -- are *rock* solid (as all UNIX 
machines should be :), and AFAIK NetBSD runs on O2 (R5000 and R10000), 
but i haven't tried yet.
