Hi SSC
... I could try to jerry rig an actual hard drive in for fun though.
I think you might be disappointed. I Googled that model last week. According to some owners of that model, there
is an open space to house a hard drive, but no cabling, connector, or electronics on the motherboard to support it.
I also read the eMMC is not something you can unplug and replace, it's soldered in.
