It is not a good idea to run Exchange and SQL and IIS on the same box. I would suggest a 3rd box for SQL and a 4th for IIS.

Or perhaps you could do this... Existing DC (stays on the same box). Exchange stays on existing Server (2), then 2 new servers - One for SQL, and the other for IIS.

We have had good success with Dell servers.
