Just as it says, MS Small Business Server 2003 Premium Edition. Its a full version, still sealed retail box. Click here for the details and specs. It includes 5 CAL's, MS Exchange Server, MS SQL, MS Outlook Office, MS Sharepoint and some other goodies along with 2003 SB Server. It retails for $1499. I'd like to get $650 for it, but I'm open to offers. If you have any questions, feel free to shoot me an email or PM.
