This WILL break the clips (if you know a better way to release them, please let us know)

Insert large flat blade screwdriver starting at points marked 1 and twist/pry to undo clips.

Then release the clips at points marked 2.

Then work your way up both sides. The cover should then (perhaps with a bit of help near the power connector) rotate and lift up from the bottom and unclip itself from the top, and come off.
