If you wanted to retain the look/feel you could replace the 120V step down transformer wth a 240V step down. The DVI Service manual does not mention the step down voltage but it might be on the transformer. You would also have to replace the AC wiring, switch and fuse holder with 240V rated cables, as well as the fuse. From the service manual that is all R/S swapped when producing the UK version (apart from the RF modulator for the TV of course :) ). The power supply board is the same – or at least it appears to be from the parts list.
The service manual is on http://www.classiccmp.org/cini/systems.htm in the M100 section.

Would it take much to replace the internal PSU with something else? <snip>
