There are lots of people who have built clusters of RPi's and other SBC's. I've got a 5-node RPi2 sitting on my desk next to me. It's fun to play with once in a while :)
AFAIK, Warewulf will not work on the RPI series. I've forgotten the exact reason but I think it's because they can't tftp boot. I've been begging Greg to do a port to RPi's, but he's pretty busy. I haven't tried the BB yet. There are some SBC's coming that are 64-bit (there are some now such as the Pine64), and some with Intel processors (udoo x86 - http://www.udoo.org/ ). I'm waiting for the udoo x86 boards to start shipping (that and the Pinebook laptop - https://www.pine64.org/?page_id=3707 ). Jeff P.S. Just don't expect great performance from some of the SBC's. The network performance and memory BW leaves something to be desired. But for $35-$100 per system, it's very affordable and lots of fun to play with.
