Build Linux Desktop ?

Hi,

Just trying to make a plan as to if this doable or not? Currently in the company all the desktop are Windows, users get MS-Word, some kind of Virus program. and all connected to Windows domain.

If I want to do the same thiing on Linux? How would I do that? First I need to create some kiind of ISO image so I can build the server fast like Windows guy. Push to each Linux user desktop.

Any one doing this in their company? Please advise.
