Just to see if I can do it, I thought I'd set up a small grid/cluster

As for the answer to your initial inquiry i would highly recommend ROCKS
Clusters that is based on CENTOS. it will automatically install and
manage your nodes from a single point (the FrontEnd server)(with NFS
shared home).
I have tried ROCKS before (granted it was maybe 6 years ago) and it
seems good if you have very lage number of nodes. If not then I would
recommend setting the things yourself. Most programs run in scientific
clusters use MPI for shared communication so you will just need MPI
setup I would not waste time job management and such as long as there is
only one person running on the cluster.
Setting up maybe 10 to 20 machines with kickstart using fedora with
openmpi, ssh-keys for easy access to nodes and nfs sharing form frontend
shouldn't be that big job. You will take same amount time learning ROCKS
and it will have lots of features you don't need.
Also if you don't use the machines all the time and don't have the
hardware yet it might be beneficial to use AWS nodes to do the
calculations. In big HPC setups the real cost of the cluster usually
comes from electricity consumption and cooling so you should factor
these costs in when deciding what to do.
