It's for the wifi not an SSD
1 x M.2 Socket 1 connector for the wireless communication module (M2_WIFI)
It's probably at the back there where those connectors are for the wifi
The ASUS Z170I PRO GAMING has M2, is ITX and has wireless as well
Thank you for the answer .
I checked Asus Website
and the picture shows that the M2 connector on the back of the board (I hope I got the picture right) , wont it overheat there?
