JIS000 worked much better for me than PH00 for these screws

This should be in the guide. The front panel is actually recessed a bit here making it much easier to get a tool in at this point. No way I would have opened it without this tip. Thanks!

I found it easier to open these clips using the pointy end of the spudger rather than the flat end. Just slide it in against the side of the case and the clip will pop off.
