Closest memory I had to these are airline meal carts, and Sony camcorders. Maybe because mine is a used and beaten up example, but the latch is too solid for an aluminum luggage case, yet seems a bit flimsy for a military hardware. The body is light for its thickness, modules have gaps not enough to rattle but enough to be able to be removed in all situations, and if disassembled, it’s obviously at least IP5X just by the looks of edge seals.

Mine is CF-19 Mark 2, a Core Duo(32bit). Takes old ThinkPad AC fine when I need a paperweight with an LCD :p
