Thanks, I know the NUC7I5DNHE is a bit higher and has a SATA slot. The one for sale is a KE, so only one slot. More generally then, in the spec for any NUC there is always a section "Expansion Options". What are these options, how do you use them?
NUC7i5DNKE is a kit without memory and drive. One M.2 slot (with key type M) may be used for connecting SSD drive, while the other M.2 slot (with key type E) is used by pre installed Wireless Module. https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/nuc-kits/NUC7i5DN_TechProdSpec.pd...
Dawson Canyon has two m.2 slots. However, only one is for storage. The second, smaller slot is pre-populated with an m.2 wifi card. That m.2 slot only supports wifi cards.
