Using Linux to Cut-Down on Tech Support Costs?

alank asks: "I am investigating a network upgrade for a school. The core Servers are Linux based, but most workstations are currently Macs or PC's and the plan is to move these over to Linux at some later date. Currently the issues on managing large numbers of WinXX programs means that considerable tech support time is wasted on fixing them. I remembered the kiosk article where someone mentioned using Assimilator for the Macintosh to keep images of the hard disks on the servers so it could be replaced, I could not find anything comprehensive on the Windows side to do the same. Should I be looking at dual booting, and somehow using linux on the clients to re-image the drives? How would you do this?
