The order shown next for removing the remaining side panels is back>front>right. It may be easier to go front+right>back.

A commenter pointed out that removing the front and right panels together while still joined is better because "the snap-fit joints between the two are easier to pull apart after removing the screws of both panels. If you want to remove the back panel before the right side […] then you have to put stress on some panels and/or joints unnecessarily."

If you'd like to try it that way, skip to Step 9 now.
