Update!
I have been in email contact with Yes Miner this past week and added one unit to my shopping cart.
Prior to making payment I requested a photo of one unit with the case open and one photo of the assemble area.

They responded they were unable to do so as per a NDA, (non disclosure agreement) !

Knowing, there is something fishy here I decided to take it a step further and have requested a friend in Hamburg to take a visit to their place next week and will update with the findings.

I wish I could understand German as I would be nice to see what their average electric bill is. ✌️
