I don't know much about Beowulf, but am interesting in building one of these:

Does anyone have one? Can you offer any insight into operating systems and BOINC with one?

I've never used Linux or done any cluster/parallel computing, but over 26 Gflops at less than $48/Gflop seems like a very good deal and incentive for my to learn.

Edit: I should have posted this in the BOINC forum. Sorry. Can someone move it?
