You can have a look at my thread "Amazon SE second time".
I was successful with that.

The biggest hurdle for me to send the package back with the knowledge that the item is missing.

However, the Amazon employee in the warehouse sees this at the earliest and he will write you a mail at the most.
And even then, not everything is lost, you just have to convince Amazon that you have no idea how this happened.

Hi! thanks, and I read your thread; I've got a few questions!

Was the pc you were SE'ing sold by a different company and only delivered by amazon?
How long did the whole process take from returning it to getting your money back?

The computer was shipped from Amazon warehouse. I had no contact with any other company if that's what you mean. (Sold and shipped by Amazon.)
It took about 1 month

Alright! thanks for the info! I'll try DNA if the OTP bypass works, then if not, I'll just do the sealed box as you mentioned!
Wish me luck
