Up today is a power Macintosh G3 Power Mac.  Model MS5183 .  I believe this is from 1999.  I purchased this from an Apple Collectors Estate Sale.  It DOES power on (by sound), but I do not have a monitor to hook it up to for further testing.  The drive ejects, but I don't have any way to test that further either.    The fan appears slow.  This will be listed as for parts or repair because I can't test it further.
