Hi again Jim,

I hope people aren't getting tired of this thread.

I think if you want to go with just a 2x dual core system (4 cores)
the Dell 2900 with Xeon 5100 cpus and 667RAM and 1333FSB should be a
very good solution. I didn't like the old Netburst Dell 6800 server
and I am a little scared of the quad core Xeon 5300 cpu cause it's so
new.

The 6950 Opteron looks nice but it will probably be louder. Rack
mounts are usually louder than towers. Plus as you said it does not
have as much storage options. I think it takes a max of 5 drives.

Personally, I don't think you really need 8 cores for 90 clients. 4
cores should be enough. So the 2900 with only dual cores should
probably be enough. But if you really want more power remember what
Les was saying about not putting everything into one box, he has lots
of experience. If you had 2 2900's with 8GB ram each, for about 60
clients each, it would offer more room to grow in the future. That's
probably what I would do. Get 2 2900's export /home from one of them
and use LDAP for auth. It would mean less bandwidth issues and your
not putting all your eggs in one basket. Plus more room to grow in the
future as you could just add another 2900 for another 60 clients. More
choices to consider....

Hope my posts help you make a better choice. I know how hard it can be
to make a good decision.
