One important consideration that I didn't see mentioned when skimming this thread on the beowulf list, is what software to use to manage the cluster. You will save yourself a LOT of time using good cluster management software.
I recommend PERCEUS (http://www.perceus.org/) but there are others you can try, such as OSCAR (http://oscar.openclustergroup.org/).
