Der8auer did some similar videos a few years ago, but in English: link ▶ this video The second is especially interesting as it demonstrates Hetzner's unique semi-custom hardware.
Hetzner is buying ASUS consumer AM5 motherboards, but with the whole CPU + memory block rotated so that the memory sticks are horizontal instead of vertical for better airflow: ▶ this video
There's some videos out there showing off their custom motherboards, it's an odd mixture of standard-ish consumer ATX but stripped down to the absolute bare essentials and with some components rearranged for better airflow in racks chassis they also build themselves: ▶ this video Another video showing the custom racks and other infrastructure: link
Hetzner also do some crazy-cool stuff, especially around the 7950X3D, cooling, AM5 etc. ( ▶ this video ). They also do some amazing stuff with ARM (their cloud offering is really solid for this).
