A:AnswerIf you are referring to the SSD, then yes. The Dell PC I purchased had a 250GB SSD, but it was an M.2 SSD which is a small circuit board that clips into the motherboard. This can be swapped out for a 512GB SSD (larger circuit board) from the motherboard.
A:Answer1. The system supports only one SSD up to 1 TB. Hence, an additional SSD could not be installed. 2. A HDD could be added, either a 2.5-inch hard-disk drive or 3.5-inch hard-disk drive, up to 2 TB.
A:AnswerYou just need the cables. I have 2 monitors connected to the back of the tower, one HDMI and one DisplayPort. Of course, your monitors need those outputs as well.
