Wasting power.
Testing ethernet and USB cables.

Mostly education. Pretty useless otherwise.

Me and a few friends got the physics dept to buy us a few RPis to build a cluster for running simulations

Photo ops.
education.
hard to get new machines for that cost per unit, so practicing setup of a distributed system is practical.
that said, the cost "per performance" is terrible so it's not for real computational benefit
