Strange rattling noise inside my 15" rMBP.

I manage to capture it today (redirect to Youtube)

It started a couple of days ago, only when I move my laptop and it lasts about 5 seconds.
What could it be ? I really don't think it's the "speaker pop sound" problem which affects other rMBP's.
Sometimes the rattling is coming from the top right side, sometimes from the bottom right side. It's like something is moving in there, and like I said before, it appears only when I move my laptop.

I have only 3 weeks left of warranty.

I really need help, guys.
The Apple Service is in the capital city, and i'm from the other side of the country (Romania).
Of course I can send the laptop in with UPS or something but If it's something loose (like a screw) I can fix it myself.

If I remove the bottom cover off to inspect it will this void my warranty ?

Oh, sorry about that. I uploaded it from my iPhone and did not realized.
Now it's public.

Thanks for the "heads up"

Sounds like a rodent.. You don't have mice?

Otherwise, most likely the fan, as it is the only moving thing in your computer. Try and get the fans to go top speed, and see if the sound can be heard.

Here's an iFixit guide that will show you how to get to the right fan.

Opening up the bottom cover would not void your warranty, Unless you accidentally damage something, like a connector, or dropping an internal part while you have it open - that will be your responsibility. Should be OK when you simply remove the bottom cover, and see what happens to fall out (or just loose)
And, I agree, running a fan utility to force the fan to full speed can also help you decide if the fan is failing.

Nope. No rats

My fans are now running at full blast.. I can't hear the sound..

Then, next step is to remove the bottom cover, and take a close look at the fan area. Tip it (carefully) upside down, while open, to check for obvious loose bits, or to see if some loose object reveals itself.

Good Luck!
