It is probably an older RS/6000 - however, I have never heard of a 550e
(then again, IBM makes a lot of weird stuff). The 500 series RS/6000s are
largish deskside towers. The desktop machines are the 200 and 300 series.

Open the thing up! If it is an old RS/6000, it will have a processor board
with eight or so big nasty looking chips - the Power RISC processor. The
only thing that may give you trouble is that the key (if it has one) must
be in the service position to get the cover off.

The RS/6000s really are nice machines, even oldies like the 320s and 930s.
