I have nearly identical tibhar case (see the first picture of the post). The outer shell is the same as mine and it's not a rigid one like aluminum case, but semi rigid made from some type of high density foam (I think it's called EVA foam) which can be compressed quite easy. It's made from the same materials like headphone cases and similar ones... My case has a lot of inner foam like aluminum cases have so its very big.
When I do my daily commute I usually take my backpack and load all my stuff for the whole day. It's quite a lot. Computer with cables and mouse, some papers, food containers, my protein shaker, my thermo coffee mug, sports clothes, shower stuff, sport shoes and so on... So now the case has the marking of my metal thermo mug pressed in it
The equipment inside survived because of a couple of centimeters of inner foam
