German police catches pedophile who was mining cryptocurrencies?

[AGD]

Found this pic of a "server room", which was made after a german pedophile Adrian V. has been arrested. To me this looks like a mining operation. Can somebody of you name the equipment shown in this picture?

I didn't think that a link to the story was necessary, because

1. My question only relies on the picture and not the story and
2. The story is completly unrelated to cryptocurrencies. Only the picture might have some relation to crypto.

This is the bitcoin part of the forum, those are definitely GPU rigs which don't mine bitcoin so this post, its picture and any replies (including mine) are off topic for this area of the forum.
