Yes, that is correct. Whether the i is written in lower or upper case is irrelevant here - it is probably just a typing error.

On this Intel support page, tips are given, where, among other things, the colour depth is also discussed: https://www.intel.de/content/www/de/de/support/articles/000029357/intel-nuc.html

It appears to be the same product. Sometimes we sell 2 identical items from 2 different suppliers.

I use a M.2 256G module from Samsung (MZVLW256HEHP) without any problems, although it is not on Intel's compatibility list (https://compatibleproducts.intel.com/)

Unfortunately, we currently have no information on when the item will be available and when we will be able to deliver it. As soon as something changes in this regard, we will post it here. Sorry.

The power supply (19V) is included.

Hallo, yes M.2 and 2.5" Drive.
