Again, it all depends on the applications themselves. I have customers that can get 50-100 users with 4GB of RAM and other that can get no more that 20 users with 4 GB of RAM. First, lets start of with what application do you plan to run on this server? What are the CPU/Memory requirements for each of these application. Will this be 25-30 users concurrently? What about using Free XenServer or Hyper-V and creating 2-3 VM on the box for additional resiliency and separation of infrastructure roles from the applications themselves?

Less? More?
