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 folding@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. -Joe
