The version 3 enclosures and hardware have been redesigned to make working on them easier.
Removing the SD Card
Four screws secure the screen to the rest of the enclosure. To access the SD card, with the unit sat on its feet remove the two screws at the top of the enclosure and the screw nearest the screen on each of the sides.
Gentle pull the screen forward taking care of the reset button fly-leads.
The SD card is located behind the white ribbon cable that drives the screen. Be careful of the ribbon when removing the SD card.
