HP netservers start at $12000! I was just there looking. For that money, I could build 10 2GHz P4 machines (fully stocked). That is why Beowolf is called the "poor man's cluster." All of the commercial clusters are geared towards business clients, not consumers. If you have the money and 3D CG is your profession, than commercial clusters would be the best and most reliable bet. But when you have to chose between a new car and a cluster, well, most of us have to side on necessity. ;0) BYS
