If I understand you correctly:

	200 sites * 2 GB/site = 400 GB

That's a problem on a single RaQ.


m> a site and a traffic of 10 gb a month.

10 GB/mo is not much traffic.  If each site has that, you'll
end up with 2000 GB/mo total, and need about 1/3 of a DS3 unless
traffic is unusually bursty or flat.  10 Mbps Ethernet probably
will be insufficient, even if switched with minimal aggregation.

Bandwidth won't be a problem, but disk will.  I don't know if CPU
will be an issue for what your client is doing.  You might try
eight or ten RaQ 550.

Or, unless there's heavy disk access, you might try a standard
Unix box with 3Ware Escalade controller and RAID5 array of
(gasp!) big IDE drives.  Much cheaper than a bunch of RaQ550.

I also like to separate services on different boxen:  DNS, DNS,
and more DNS run on their own machines.  Other machines perform
MX service.  Web servers are separate yet.  Then database
servers.  Still a different set of boxen for Kerberos... and so
on.

Can you give more details on what's required?
