I always hate to hear of a perfectly functional computer (especially such beautiful ones!) being gutted, but I also totally understand the need to reduce the footprint, and the difficulty in selling such heavy items.
With as many eMacs as you have, and if you felt the need, you could probably donate an entire computer lab to a local school. Sadly though (in my experience at least), the IT folks at schools often don't understand that a computer's usability, even for current tasks, is not directly determined by the year it was produced.
