I have a Dell server with SBS 2003. I plan to purchase a new server from Dell with the OS preinstalled. My question is should I have SBS 2011 or Server 2012 installed?
That is going to depend on what you want the server to do.
If you are going to use it for AC, you are probably going to also use it for file sharing.
For example, do you want to use and administrate Exchange?
How many users will be on the system?
The feature set you need and the number of licenses you want to pay for will drive the decision.
