A:Answer Yes, I just opened it up a moment ago for the first time, and there are additional sata connectors and an additional bay, but the PSU is not modular, and therefore does not have an additional power connector for another drive. The super odd thing about this computer is the fact that there are TWO drives installed already. Only one is advertised. There is an m.2 on the motherboard, and a 2.5" SSD in one of the two drive bays. I haven't torn it or apart or turned it on to see what exact drive is there yet, but it's absolutely bizarre that there is no mention of the second drive whatsoever.
