To the upper right is a 2 bay SATA dock. It's served me pretty well. Just drop the HDD in and turn it on. As far as the RAM specs, they listed each slot capped at 16GB, so even one 32GB shouldn't have worked. This is my first foray into Windows10 outside of my work laptop, which I can't really customize or install a lot of things. I'm kinda missing Win7 a little, but I'll give it some time. I can't get my S20 Ultra to connect yet. One weird thing, when I was waiting for the new laptop to arrive, I hooked my work laptop up the the HDD dock, and it would have occasional hiccups and short freezes when playing video from an external drive, which no Win7 machine ever did. And now the new laptop does the same thing on occasion. IDK what it is with Win10 and those external drives. I have an NVMe to USB adapter coming so I can clone the 256GB SSD onto a 2TB one. 256GB is so 2005.
