How is NZXT on keeping your data secure during repairs?

So I'm sending my PC in for repair (power cycling during high loads) and I was wondering: what is their track record when it comes to keeping my data safe? I would love to possibly clone my SSD but of course sending it to strangers makes me feel a bit paranoid.

Edit: If nothing else I have my files backed up to an external HDD in case I have to factory reset. Just not everything is backed up like Steam games, etc.
