$48/Gflop Supercomputer w/low power, too

Calvin CS professor Joel Adams and senior Tim Brom have designed and built an inexpensive (~ $1300) 26 Gflop supercomputer called Microwulf (a play on Beowulf, referring to a cluster of Linux nodes). The machine as it now stands has eight nodes, but can be updated to 16 by replacing the processors. Microwulf consumes only 450W at full load.
