you can also often find a white-box manufacture which is willing to let
you remotely evalute a compriable Xeon DP and AMD Series 2xx machine to
run your code on to perform pre-sales tests.

my answers is slightly biased.. as i work for a white-box vendor now but
in my past life as a unix sysadmin i've bought from the big guys and the
small guys who had past cluster experience and i've ALWAYS had better luck
with the small guys.  you will often find the small guys providing you
with a more complete solution, instead of just a bunch of hardware and the
option to buy a consulting services to perform the software installs.

otherwise ... i agree with the following recommendations, especially the
$2K per dual proc server price point.
