This was my previous question:
what should I look for in a board that makes it a "server" board? I like the recommendation Choward made, but, we don't need that much of a server. I would like help in selecting a board and processor for my next server build. Is anyone up to helping with that?
Max outside users logged into the web page interface at one time is 25.
Server will run SQL and Exchange
Will use a second machine for file serving.
Am open to Virtual Machine, but may explore that in another question.
