I am a Linux beginner also but I have done this in the last week.
I used Ubuntu 11.10 and Fog 0.32 and isc-dhcp-server 4.2.2. After a couple days and headaches I got it to work. Mostly because of my knowledge of Linux at the moment. I ran into a number of issues along the way but if you went this route, I could try and give a hand if you ran into any problems.
This is a great setup for standalone imaging. This configuration could be used to image one PC connected to the NIC of my Fog server, or multicast multiple PCs connected to a switch and the Fog server.
