IBM PowerStation 530

The other day, my University (U of M @ A^2) threw away an old PowerStation 530. Having never seen anything like it before, I grabbed it up and carted it to my dorm room (alone). I've never really seen anything this old, and I'm not sure if this behemoth is even worth keeping. Perhaps it could replace my current Pentium I 110MHz (24MB RAM) as a server, but I'm not sure. Anyway, anyone here have any experience with these machines? Know where I can get a manual? I've only been a computer geek for about... oh... 6 years now, so I've never seen the monitor hook-up either... it's mini-coax and looks like the diagram below: (o)(o)(o) I'm assuming that's RGB... Thanks in advance for any and all help. Now, back to trolling. :o)
