Building a home cluster - hardware and cost analysis [closed]

Does anyone know some links / books / anything you can think of, that describe the process of building a little home cluster (when I say home, it doesn't necessarily mean for keeping at home - just means it's relatively cheap and small) for experimental purposes, with a special emphasis on what hardware would be adequate today, and some kind of cost analysis ?

Although, if someone here's done it, I'd appreciate all the experience you can share.


Solution 1:

Helmer comes to mind. :)

Solution 2:

There have been a couple of Ikea clusters featured on Hack A Day:

  • 24 core
  • Helmer
