That's basically a car pushing out on the lid, a car on the bottom, 3 pushing out over the walls, unless I missed something with my math. Staggeringly more than I would have imagined.
There's a reason for the multiple redundant safeties on these things.
Fisrst of all... the statement "That's basically a car pushing out on the lid, a car on the bottom, 3 pushing out over the walls" it's completly incorrect. Force of the pressure on lid, bottom is equal in all directions...

Outward force, net force is 0 unless something happens. Sure, even the net outward force would be 0, in terms of accelerating the entire PC. The concern is the internal forces. And since the lid is orthogonal to the walls, the force of the pressure upward on it is roughly equal to a car. trying to push it up off the PC with just the locking lugs holding it together.

I spawned some popcorn casings and had double-overlay cause I didn't put enough hydrogen peroxide in my automated aquarium mister. I only got one mushroom so I cut off the head part where the seeds fall from and put it in a jar of LC and sprayed it all over a tin of PF cakes I made with gravel, cardboard, and bisquick in my microwave. I think it will be good cause B+ is so potent. Triggered yet? Only a square would say "a cube is a cube."
No, this does not look right...
