Caveat: my mom is 76.
Yeah, I don't know why I didn't see what I was doing was wrong. Mea culpa. The cable management was not great, but when I close the completely opaque case-problem solved! :)
I have only used it a little, but I really like it so far. There is good travel and click feel. It IS noisy compared to non-mechanical though, so be aware. The fonts look like something from the Matrix or Terminator movies, but they are very legible, and my mom loves that they light up for night visibility.
The upper slot is x4 PCI Express® lanes, the lower one is only 2.
