You would need to post motherboard and chipset specs for each machine, as that will determine what images you need, and what patches you need to apply to them dumb@ss.
There are no versions of OS X that run on a pentium. Core 2 and up, only. There are versions that run on AMD systems, but most of them are crap and things like USB and sound won't work.
Or, just go to the Apple store and buy a copy of snow leopard, as it installs without a hitch on any new PC. Saves you hours of work, literally.
