The top view is mirrored as though you'd be looking through the PCB.
The flipped side, with the illustrated connector, would be as if viewed through the sheet metal on the opposite side of the box.
Same for the "side view at the top.
I like to print out boxes so that they can be folded and viewed for the outside as if looking with X-Ray Vision.

Cooling will be accomplished by mounting a largish fan undernearth the FDD, blowing out the bottom of the case.
Standard galvanized ductwork will lead from the fan to the spot noted on the front of the PSU's sheet metal.
The PSU's PCB solder side will be facing up, with an airflow re-dirtect vane causing the air drawn in the top vents to flow toward the back of the IIsi's PSU sheet metal. It'll then be pulled down across my adapter board and back through the ATX PSU, then pulled out the front by the ducted fan. The entire assembly will be just about as stealth as possible for getting 250W of continuous power in there, with gonzo 5V to run the Rocket and as many NuBus/PDS cards as I can address and cram inside and under the lowly IIsi's case.
