(I asked Jan if he had any photos of the MDD Pwr Supply Mounting in the older Macs and he sent 6 images below. Update: Another reader sent photos with explanations on mounting the MDD PS in a Quicksilver)

sorry, these pics come late, but I had a lot to do... But here they are, the mounting area pictures. Pretty much self-explanatory, as I think. (I asked he send at least a sentence for each photo to clarify what is shown, as some are not really self-explanitory.)
If there are any more questions, please feel free to contact me again, may take some time though :-)
