Also keep in mind Xeon 2.0 has a much slower bus than the new generation 2.4. Always go for that one instead of 2.0. For the rest liquidmoe was right.

Yes, large DB's should have lots of RAM. However, I've personally played with multi hundred Gig databases. Trust me, you need fast disk, with good seek times. Remember, you have to get your data off the disk, down the bus, and into ram before you can use it.
RAID is NOT interesting if you need 'speed' alone. In fact in many cases RAID will slow you down, but in those cases the integrity of your data is/should be more important to you.
Should probably throw out here that I deal with a LOT of solaris and linux machines, some free/open bsd, and very little windows.
