I received the kit free of charge after exactly 15 days. They must have been closed in Hamburg over Christmas/New Year.

Thanks for the answer Sven. Unfortunately Digitec doesn't allow it yet, I would have liked to attach a photo. The backplate really doesn't fit. Unfortunately the support leaves a lot to be desired. I was able to order directly from Enermax on Wednesday evening: https://www.enermaxeu.com/de...

I will contact you again when the part arrives.

@Digitec, can you please add the links to the different kits for the coolers?

You should be able to install the water cooling system without any further purchases.
