looking for a imac to LTSP thin client howto

[john]

Hello all,

I want to use our old crop of imacs (blue case front loading, white
case front loading) as thin clients. I keep reading it can be done,
and I've found bits and pieces lying around the internet but no
definative howto.

I am running ubuntu 8.04 LTS can someone let me know the steps
involved in order to get imacs to boot up into an LTSP environment?

Thanks!

John
