When I got it I looked it over and it appeared to be in new condition.  Hopefully they slapped a whole new keyboard onto it.Ran it and checked it, then immediately swapped ram and m.2 drives with an previous gen (7th gen) dell latitutude I had upgraded with 32gb ddr4-2400 and an nvme.  After playing around to get the uefi to like the linux install I had on there (blame microsoft, but at least it worked), it seems to run fine.  I did have to turn off power management of the different nvme but otherwise it's been working well although I haven't yet stress tested it.
