PSU: cut the big hole out, Drill 4 mounting holes, and screw. No further support...
It can't fall far, it's too crowded in there.
HD: I rounded my cables, which made them a tad shorter. Even full length, it would have been a difficult reach. I kept the HD bracket intact, and just laid it horizontally where the PSU was. Now my bottom PSU fan helps cool my HDs.
you can mod the PSU fan to make it quieter. just unplug the psu fan from inside the PSU, or from the mobo if you're lucky, add some wire to the leads, and run it through a rheostat to lower the fan speed. You could also run it at 7v by simply using the 5v rail as the ground, and the 12v rail as the hot wire.
no photos, but this should help...
