Yes, it can be accomplished, the SSD 2.5 in port on will have to have the case removed from the circuit board. Look way back in the forum and you'll find all this info and which SSD you need to use. One member even printed out a caddy to hold the M.2. Slot 1 will have to hold an M.2 and a 2.5 SSD port 2 is SATA 2 so it doesn't matter what you put in there.
