Just a note for Indy owners who would like to keep their machines in good physical condition.  On my example I found that the lower drive sled (normally the HD) covers the right side cover retention notch and that can lead to the delicate plastic tabs on the cover being snapped off when the computer is lifted by the sides.  This was clearly an oversight and may have been corrected in later production.

It's fairly easy to mark out the interference on the sled viewed through the open slot and then after disassembly carefully cut away the steel. 
If the mating plastic tabs are broken off, fabricate two L-shaped replacements out of 2mm thick aluminium bar and epoxy them in-between the remaining ribs.
