Moving bootable XP HDD to another computer

Ok, so here's the situation. A customer came in with a bricked computer, bought a new one, and wants to see if I can just pull the HDD out of his old computer (custom build) and put it into his new Optiplex 755. That won't work as stated since IDE HDDs won't physically fit in an Optiplex once you put an IDE/SATA adapter on them (The 755 doesn't come with an IDE controller), so I imaged his old HDD onto the 755 HDD. My plan was to either boot into safe mode and take out the drivers or do a repair install. However, whenever I boot the computer, it BSODs, in both scenarios (Yes, even when trying to boot to a Windows CD-it BSODs when it gets to the 'Loading Windows' bit).

However, the HDD WILL boot off one of our old shop computers. I started removing old drivers, but the drivers are so messed-up by this point that I can't tell what's from the shop PC and what's from the old PC. I suspect that the main sticking point is the chipset drivers-the old machine is an AMD, and the 755 is an Intel. But so is the shop PC...

Anyways, any advice here? Is this do-able, or should I be telling the guy 'too bad, all I can do is back up your stuff.'?
