Alright... Never mind... After about 2 hours of poking at it and getting my fingers sandwiched, I finally figured it out. It's actually pretty easy to disassemble once you know where to look.
Basically, this is one of those screwless cases. There's only two places holding it together, the front and the back. There are no hooks in the middle.
First thing to do is remove the front face. There are four hooks on the front, as seen in picture 01. This can be done by lowering the tray door and pushing out on the edge of the front door assembly. Press either up or down. The front case assembly rim is pretty flexible. The other side will pop off easily once one side is off.
At the bottom, remove the two front rubber feet, and then remove the two screws, as seen in picture 02. These screw the bottom of the drive to the bottom of the case.
The other place the case is hooked up is the back. There are two places in the back. Look at picture 03. There should be something that looks like the emergency eject holes. Stick an emergency eject tool or a paper clip into the hole.
You should be able to take the bottom case off as shown in picture 04. Notice the little tabs at the back. That's what's holding the case together.
Finally remove the metal shield by lifting the tabs at the side as shown.
You should be be now be able to see the IDE-USB circuit board, picture 05.
Unplug the IDE cable and molex power and now you're done, picture 06.
