[GRASSLIST:5184] Hardware configuration

What is the best HW configuration to run grass on?
We are planing to buy Dell Precision 670-MT
(dual 2,8 Ghz Intell processor, DDR2 memory, 2 x 36 GB HD ... with pre installed Rad Hat linux)
What do you think ? Any suggestions? Any experiances to share ?
we are planing to run grass an UMN Mapserver on it.
