The guy discredits himself when he starts pointing to the calendar being turned to the wrong month in one of the pictures, and to the way the kid is supposedly squatting like a Russian, or that he has a mole on his hand in one photo and not the other which could be anything from a burn to a scratch to whatever. (Most of this is in part 2 of the video)

As for the first part, that isn't even a motherboard on his bed, and as other people have said there is nothing strange about the flagpole or shadows if you're experienced with analyzing pictures in photoshop.

I hate guys like this that pretend to be an expert in so many areas at once, yet with some basic knowledge you can disprove everything they are saying.
