Usually, processors are not critical, although they are important. A
dual PP200 should be fine for moderate to heavy loads,

The more spindles the better. As your Database grows, a single
harddrive will be a major bottle neck. You should look into hardware
RAID with atleast 3-4 drivers for better performance.

SQL Server loves RAM. The more the better. Thats probably #1 on my
list. Secondly is driver spindles, followed closely by CPU speed.
