This year's state of the art would be a rack full of
Dual Athlon systems. By this fall they will be
available in a 1U form factor at 1.4Ghz. Each
CPU produces 2 Gflops. A dual-CPU system is then
4 Gflops, and you can pack about 32 1U systems in
a rack, for 128 Gflops in a 1 rack space. Initially
these systems will go for around $3K each, so you
can figure about $100K for a rack full.

If you are going for maximum processing capacity
per dollar rather than per cubic meter, you can
already build a cluster out of desktop PC parts
for around $500-1000 per node, giving you $250-500/
Gflop, or $250K-500K/Teraflop. The major variable
is how much RAM and hard disk per node you buy.
