Download details: Moving Data Folders for Windows SBS 2003
I have been looking for a document like this. The default installation and the OEM installation of SBS2K-SBS2K3 puts everything on the same partition as the operating system. I have already moved some stuff(e.g. SQL Server) by researching it. This document has instructions on how to move several other items and it has all the instructions in one place. Thanks go to someone on the SBS mailing list for mentioning this document.
