(1/2) M.2

question:

1 can you please tell me what kind of M.2 SSD could fit this slot?

2 if I use new install the win 10, how can I activate it?

 

I have checked the answer, for  ATC-780 M2ssd slots, http://community.acer.com/t5/Aspire-Desktops/ATC-780-M2ssd-slots/m-p/484461#M10437

• 1x M.2 (2280) for SSD SATA 3.0
• 1x M.2 (2230) for Wlan board

but I dont know what the difference with the ATC-780 and  ATC-780A-UR12. I saw the ATC-780A-UR12 mainboard, the empty one M.2 is a little bit short than 2280, I wanna upgrade to ssd,  can you please tell me what kind of M.2 SSD could fit this slot?
