I have a naive question. I checked out the other link tot he DIY rack, pretty cool.

Are all 6 computers the same? networked together? = 1 big super computer? or do all 6 just work independently?

Sorry if it's a stupid question, I am just not very knowledgeable in the network computing and was kinda curious. I have 2 other computers from family members sitting, a little older, and was wondering if its even worth it to try and combine. The computer I have now is a quad with 12gigs of ram.

cheers,
