Correct way of standing PS4 vertically?

I'm standing my PS4 next to my TV vertically, but the catch is, the "PS" logo is upside down rather than rightside up...contrary to all the pics of vertical PS4s I've seen :

(Image the vertical picture above with the "Sony" logo on bottom rather than on top.)

Is this incorrect and/or known to cause any problems? It has to stand that way for me to properly load discs. But even with that, should it sit horizontally?

Does no one know?

I don't know if there's supposed to be a correct way to have it stand up but I've always seen the glossy finish part on the top in any pictures I've seen

Glossy part up is the right way.

I found that standing it vertically made the fan a lot louder, so I put it horizontally. YMMV.

I never trust a vertical system. Pretty sure though that it doesn't matter which side is up as long as it doesn't disrupt the heating vents.

In the past, I've had issues with discs being scratched when standing a system vetically; so I just don't do it.

With that said, I believe that one side of the PS4 has little feet that are intended to be used if you decide to stand it up. Put the Shiny side up for the intended orientation.

There is a stand they make for the thing that I believe isn't sold in America.
