Good morning, I recently aquired this model and started reading the manuals found in the page when I came across with some info about the storage capacity:

"Your computer supports one 2.5-inch hard drive and one M.2 2230/2280 solid state drive."

Albeit I'm unsure about this meaning either I can use my default 512 gb SSD as much as an HDD or if I can install and use both drives with the HDD as secondary. Since I haven't performed a disassembly I'd like to know if the motherboard counts with an additional port or if i'd have to go through other modifications to install a second drive.

Also I would like to know if there is a manual or datasheet about the motherboard. Thank you.
