How do I open this?

[Atmosphere]

Got it, thanks! Would you by any chance know where to go from here? It's open but I don't see any more tabs or anything I can pry on or unscrew.

Here's where I'm at:



EDIT: I think I got it, currently turning those little metal contacts and working my way up to the switches.

EDIT 2: Finally got it, on to testing!
