As long as you pad the suitcases on the inside with stuff like towels or similar so that the components don't have space to move around and bang into eachother, the unopened boxed should let your components go through pretty much unharmed.
My brother knows a lot about computers so im sure he wont pack them badly but he said "managed to fit" so maybe there is no room for towels and stuff? Plus, He's not going to bring towels, and he also said for his clothes hes getting a small bag so i think the parts are in there alone...well these are the parts so maybe there will not be any room for them to move
