Moving Home - Shipping the EX4

We are moving home from US to Europe and the EX4 will be shipped.
Does anyone have suggestions about shipping the EX4 and the drives?
Should the drives be taken out, or left in?

IMHO, unless you have the original packaging with all the inserts and padding, I’d remove each drive, put it them in individual antistatic bags, and bubble-wrap the heck out of everything.

That’s pretty much where I am. I’m backing it all up, so I won’t loose anything.
