[R] Which is the best hardware?

[Kenneth Cabrera]

Hi R users:

In your opinion and experience, which hardware configuration
is the best to run R over LINUX ?

With "best" I mean best performance,
and also cheapest. (about U$ 2.000 the whole basic system:
mother board+CPUs+RAM+HD)

By the way, which LINUX distribution is the best to
run R with high computing technics (simulation, bayesian, etc) and huge 
data base?
and in combination with what kind of (cheap) hardware?

Thank you very much for your help.

Kenneth

Happy Holydays!!!
