How do y'all suggest I put to good use the increasing number of extra

You would think I was starting a computer museum with the number of
decommissioned computers I have at home. A few Macintoshes and a couple of
Intel-based machines. (Not to mention the TI-99A, or whatever.) I don't
really need backup. I don't really need a Web server. Maybe I could use
these computers as some sort of CPU Farm to do some sort of interesting
computing.
If your collection is anything like the number of machines that I have
collecting in my basement, they might be okay for people learning how to
set up networks and the like, but they're a waste of money as a comute
farm.
The problem is, they're older processors which offer less performance per
watt compared to today's machines. You're often better off buying new,
low-end hardware if you're going to be running fold...@home 24x7 than
running it on machines more than a few years old.
Other than 'learning to connect lots of machines' aspect (for which most
of my machines are just too old to even make that worthwhile), the only
other use for old hardware is to convert it into appliance-type machines
where you don't quite need top-of-the line specs. Eg, the emulator in an
arcade cabinet isn't going to come near pegging a modern CPU; a small BSD
box to act as a file/music server or a small HTTP server for testing.
Now, it's possible that your machines aren't quite as old as mine ... and
I have a few PPC macintoshes, but also some 68030 and 68040 machines, some
old AMD and Intel boxes, and even a few pre-sparc suns and a Vic 20.
