it is for oem production actually , part of the reason i am avoiding extra tools.... i was seperating out program files, user profiles, to the c drive, and it worked great except for the fat partition part, i was looking more and i think the conversion will be fine because it is going to be the largest partition anyways.... basically making a disk that does both install and reinstall, and keeping the old user accounts via registry backups etc..... if it works i will post links to my downloads when i finish.... but i am working on this for an actuall vendor so i have to keep some wraps on the details... even though most people on this site already know how to do this... but for some reason the current major oem vendors haven't.... poor home users....
