Disassembly

The right way to start would be to peel the sticker off the bottom of the unit and remove the two screws hidden undernearth. It is important to figure a way to remove the sides without disturbing the anti-tamper jumpers. I am told that if you power the unit up without these jumpers (or with the jumpers reinstalled improperly) the unit will brick itself.

I had no idea about the screws and had no qualms about destroying the case, so I began by using a cutoff disk in my trusty dremel tool to saw off the top of the case.

If I had it to do again, I would cut the sides in the places I marked (for your convenience, dear reader) to avoid pulling the anti-tamper jumpers.

Below is a photo of the "jumper puller". I am going to provide photos showing the location of the jumpers to aid people who may want to chop into their case (assuming they have the new model) in an attempt to remove the PCB with the jumpers intact. Note that it may be possible to disconnect the "puller" from the case side with some kind of long tool.

Below is a photo of location of the jumpers on the front of the board.
