Jeff Layton and I used Warewulf for the Kronos Cluster
(www.clusterworld.com/value_cluster.shtml) for this reason.  The Kronos
cluster is a series in ClusterWorld that explains how to build a low cost
cluster ($2500), install WW, install other tools, and make sure the system 
works. It is a recipe that can be altered to the users taste.

Here are a few comments about WW. First, it is a great method to manage
clusters (using RAM disk on the nodes, so it can be used diskless or
diskfull). It simplifies management. Second it is quite easy and painless
to test new things. Now, that said, WW is also undergoing development and
there are some rough edges that need smoothed out when installing and
using it (we address all this in the magazine series). Plus the mailing
list is very responsive. Right now it is not a "turn-key" cluster
management system but it is headed that way. Indeed, there is some
discussion about a "Warewulf IS (Industrial Strength)" development branch
that would address package integration, documentation, and usability
