I actually asked something similar months ago. A couple of things come to
mind, though:
1) is this some kind of internal website - only 40 user sessions? If
so, the basic configurations will handle way more than that.
2) are you 150% positive it will only ever need to support 40 user
sessions, and that a year from now, they won't want to let
400 or 4000 users on?
3) Is there budget for more than one physical server?
For my points 1 & 2, you should *always* plan for max usage, not median,
so overspec. For my point 3, for a real production system, I'd have the
web server on one box, and the d/b on another. And a third, running both,
for development and q/a. The latter doesn't need to be as heavy as the
production boxes, though.
*Maybe*, for such a small operation, you might be able to get away with
one production box for all.
Oh, and think about what happens if you loose something - what's the
impact of downtime if a drive goes out, or a NIC?
