I am gathering more information on the computer cluster and I have determined that I can build a mini-supercomputer for less than $10,000. Here is the configuration of each of the client machines that I am pondering: Motherboard: ASUS P2PE Intel 845e Chipset ($120) CPU: Intel 3.08ghz Pentium IV ($250) Memory: 2700 533mhz 1 Gig Modules ($150) Network: FiberOptic 1gigahertz ($150) Hard-Drive: 20 Gigabyte ($40) Case: $50 Total cost for client machine: approx. $750 10 machines would run around $7,500 I don't need video-cards since the motherboard has in intergrated one. I also don't need monitors since I can log into them from the server. Linux is free.
