Pelican case with the hardware. Your carry on or backpack with the data. Think about journalists and photographers, they do that every day (my uncle was a cameramen). Ask to them. Call to the embassy or the airport security, they are not always a bunch of jerks. Be honest at customs, depend on the country they could want to access the data (even when they just see the desktop or just some pictures). Don't check anything that you are not ok loosing it.. I travelled with some cameras, notebooks, tablets, hard drives using that (pelican with some padlocks, 2 different brands and systems on each lock.., I really hate airports, they stole my Adventure Time tag) and an Oggio renegade backpack.
