    Samer,
    This is such an open ended question that we cannot really answer!
    To help, can you tell us:
    How many sites?
    Roughly how many users at each site?
    Roughly what volume of data?
    What internet & inter-site connectivity?
    What server OS you are wanting (2003 or 2008 )?
    Anything else you think might help?

    Others will advise you (and quite rightly so) that your best bet -- especially if you have the unlimited budget you appear to have -- is to get a good consultant (Hi Sembee ) to come and analyse your environment and recommend. All we can do is guess from your information and I personally would hate to make a very expensive decision on that basis!

          20 user , but there is no server room in the 2'nd site because of that installation of servers must be in head quarter only

              OK
              For the second site you have either:
              MAPI over your 64Kbit line or Outlook Anywhere over the ADSL -- 20 users should be no problem on either option

              For the main site you would probably want
              A cluster of 2 servers (plus the witness server) with the mailbox role and some sort of NAS/SAN device they can talk to
              CAS and HT roles are, IMHO, less critical since they change rarely and can be restored quickly with a good backup solution, but you could have two of each
              Edge transport is (again IMHO) a waste of a license, but you say you have licenses to burn

              Of course, with a good NAS/SAN you could virtualise all the roles and have them fail over to another blade if the main one fails -- this may be worth looking at

              Disclaimer -- others here have considerably more E2007 expertise than me, so listen to their opinions too
