[opensuse] Linux equivalent to Win SBS

Sorry, probably off topic (please point me in the right direction). Work is looking at reinventing itself... and are investigating setting up a (basically new - ie not an upgrade to our existing 2xWindows2003 Server Std + Exchange + AD) Windows SBS 2011 System with up to 50 users. This would entail a head office with 2 branch offices which I would imagine would be interconnected using VPN. Main services would be Active Directory/File + Print/Email+CalendarEtc/Sharepoint/Backup/ Where can I get advise/info on the best approach for designing/setting up an equivalent system using opensuse/Linux?
