I think you can if you switch the power supply as well. If i remember correctly the 1.2/1.3 have 2 rows of connector thingies (yes thats a technical term) for the power supply to connect to the MB and the 1.0/1.1 only have 1 row. Look around at www.xbox-scene.com for some pictures of the 2 different MBs, and you should see what i mean.
yes dont see why not they all use the same connectors for the hdd and dvd-rom as far as i know....maybe i dont know much! but as the other guy mentioned, i think the only difference that may affect it is the power supply, but i think you should be ok
