"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Looks good, also include Redundancy requirements.

1. Do you require redundancy on your CAS Server (CAS Array)
2. Do you require redundancy on your Mailbox Server (DAG)

Both of these will require additional servers.

Also find out when the current certificate will expire so you know if you should include a SSL UCC certificate.
