I always have the same idea when I replace my old machines, but eventually I just recycle them or give them away. Usually the hardware I'm replacing it is so much faster that using the old machine as a compile farm or something like that doesn't make sense. Using it in a robot or something sounds fun, but I'm more likely to use a Rasberry Pi or Arduino for that. Could use it to play with distributed computing, but even that might be easier using a couple VMs on your new machine.
