Anecdotally, in a different market, we build 4 and 8 core desktop
machines for customers with 8->32 GB ram, as frontends for their
clusters.  We find that users like running smaller jobs on these
machines, and submit larger ones to the clusters.  These customers are
even running their Windows desktops virtually using VMWare sessions.

I am working on an 8-core desktop unit now, doing some additional
testing with it.  Small SMP units like this are really nice to have to
do work on IMO.

This is similar to our design.  4x500 GB units in a RAID10.  Redundancy
and speed.
