iTX Clustering Project "Green"

So I have a concept for a 24 node cluster, I want to build to run folding@home and other cancer research projects

The spec is to make it as “green” as possible, the lower the watts/ghz the better, whilst still maintinaing performance.

The downside is the pricing of pico-ITX at the moment, I’m getting quotes for about £200 / node … and that’s without ram, or storage …

What I need is the following.

pico-ITX form factor motherboard with ~1ghz CPU, in quantities of 5 or more

So please leave a comment or use the contact me form if you think you can help, or have any information on suppliers.
