Whistler server, and console mode

I was wondering if Whistler.net had a startupmode that was only a textbased console. And it had to start the services of cource.
I have a server and if the GUI runs, it use a lot of resources on that. And the only thing I want the server to do is run it's services.
Is this possible?

I just thought of something. If the services are loaded before the Login screen, the OS can just boot and then stand at the Login screen. Then Explorer.exe arent loaded.

thanks mate
