[Beowulf] Similar to a multi CPU machine?

I've heard of many of these(Scyld, OpenMosix, etc.) Since this is how it will 
work, will I be able to use these 6 machines as a workstation? I understand 
that the CPU power will be next to none, and I have read your book about 
overhead, and feasability and so forth. Having not done the calculations, I 
have a pretty good feeling that my computers will not meet the standards for 
them to actually be useful. I'm a high school student, and would like a 
multi-CPU machine to play w/, but I don't want to spend the money. Thanks 
again.
