You can actually install the Server Essentials Experience role on Windows Server Standard or Datacenter.
This will give you the "experience" (basically the features and tools) like you are using a a Server Essentials server but you can run it under your Standard or Datacenter license.
To do this:
-Log on to your server as a local administrator.
-Open Server Manager, and then click Add Roles and Features.
-In Select server roles, select the Windows Server Essentials Experience role. In the dialog box, click Add Features, and then click Next.
-In Features, click Next.
-Review the Windows Server Essentials Experience role description, and then click Next.
-In the pages that follow, click Next, and then on the confirmation page, click Install.
-After the installation is complete, Windows Server Essentials Experience should be listed as a server role in Server Manager.
-In the flag notification area in Server Manager, click the flag, and then click Configure Windows Server Essentials.
