My first Cherry MX 5000 was the G80-5000HAAUS model.

I picked up another one. This one is the G80-5000HAMUS.

Differences:

The HAMUS is newer and has the Windows keys. Other than that, the main unit is completely the same built, only the label is different.

The Windows keys are not double shot. The other keys are. On the HAAUS all keys are double shot.

The numpads are very different. The older one has Cherry Browns and double shot keys, the newer ones has low travel switches and no double shot keys, and a couple of relegendable keys.

This numpad does not have the problems of the 4100 and 4400 Cherry board with the sticking corners of keys. Not as good as the older numpad though. It's hard to distinguish the legends from true double-shot.

Two broken off feet. Seems the previous owner already tried to repair it with glue, it's a bit of a mess. It was in the ad, and for 10 EUR I'm not complaining.

Cheap sticker. I wonder if my older one had a sticker logo once, but it shows no trails.

The keys on the left use super strong switches, they look like MX blacks, but they are not.

The wit-o-meter could barely manage this!

Over 150g. It didn't even completely bottom out yet, it's half way. Someone at Cherry was pretty scared to accidentally press these...
It's officially the heaviest switch in my collection.
