Pedro,

You've gotten some good advice on this thread, so I won't reproduce it, but
you
are well advised to take your time to read up on Beowulf clusters.  There's
even been a book or two written, so get one.  But, scyld from what I've
heard
runs well out of the box.

Can't stress enough the importance of laying out your infrastructure. You
can make the 
assumption, given a budget, that you can get the equipment (that's kind of
the point of 
a Beowulf).  But, you really need to focus first on the data you're working
with, whether
or not it can be manipulated using parallel programming -vs- distributed
techniques, and
how much data you expect to work with.  Once you have that, pick your
hardware.  Plan on
getting some upper end PC's $1000 - $2000 range, some good networking
equipment like switches
and cards (if the cards are not integrated into the motherboards), and be
sure to find a room
with *good* air conditioning (or build the cluster next to an iceberg).
That's a *VERY SIMPLE*
explanation. 

If you need help beyond that, contact me offline and I can help.  

Of course, you should search this list's archives for hints on hardware,
benchmarking, etc . . .
