As the heading indicates, I did not research this well, and thought it was an updated 2018 version of this excellent little desktop that I used for years in a former workplace. It is not. The architecture won't permit me to upgrade the hard drive above 2 TB, and thus far, I am unable to get a 5G dongle to work correctly, and am stuck with slower internet. Don't be sucked in by the "2018" in the listing! An additional point: Amazon is allowing multiple vendors to sell this within the same listing, which is why there is such a variance in the reviews. I find this to be a little shady on Amazon's part! My supplier was evidently one of the good ones, because my machine has had no flaws, does not smell smoky, and was perfectly clean inside.
