lanl's web page says the per node price was under $1k.  So with 294 nodes and
a $500k total price, they've still got over $100k to spend on switches and
wire racks.

Still, their configuration doesn't seem like it would be the most cost
effective to me.  A 1U or 2U rack case is just as dense as those shuttle
boxes.  With a dual CPU board you could get by with half the number of Gb
switch ports, which aren't cheap for >24 port switches.
