[Linux-cluster] hardware suggestions for a simple cluster

[Geoffrey]

I'm hoping to put together a simple two machine cluster with some kind 
of shared disk.  This is simply so that I can get some hands on 
experience with a cluster.  The plan is to cluster the two machines, 
then run xen virtual machines on top of that.

As I'm self employed, the key here is the best price.  It doesn't have 
to be the best solution, but a workable one that will give me practical 
experience.

Suggestions would be greatly appreciated.
