Finding the screws and the correct order to disassemble this monster is a real nightmare. Good job on creating this tutorial.

In my experience the easiest way to remove the panels is going in the following order: top, left, front+right, back, bottom. It's easier to deal with the front and right panels at the same time: 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 (as recommended in the guide) then you have to put stress on some panels and/or joints unnecessarily.

I didn't need a flat head screwdriver to deal with the joints but in general it's better to use softer plastic tools for that. Those leave smaller marks or no marks on the plastic case compared to a hard metal flat-head screwdriver. A lot of precision screwdriver sets and mobile phone repair kits come with those plastic tools that look like mini crowbars and guitar picks.
