Make sure to take apart your webcam and see if the board matches the one shown in the image. I'm not sure how else to identify the model; if you have any ideas please leave a comment. The case snaps shut, but should still be easy enough to take apart if needed. 

Assembly:

1. Take apart the original webcam housing. There should be a microphone connected to the front half, so be careful in removing it.
2. Unscrew the 4 screws connecting the PCB to the case. Use the same 4 screws to attach the PCB into your new case.
3. While keeping the two halves near, fit the mic into the front half of the case. It should pressure-fit in, but depending on your tolerances you might need to adjust the hole or use glue.
4. Close the case, making sure that the cable is in its slot. It should just snap shut!

Make sure your PCB is 30.3x25.1mm, designed roughly as shown.
