I dropped a full glass of milk on it. Took 2 hours to completely disassemble, clean, and reassemble it. It looks just like when I had it. Thanks !

A few additional points:

* If you also need to remove the lower cover from the board, the operation has a few tricky bits:

** The full-size version of the keyboard has two plastic hooks holding the cover to the board and there is no obvious way to release them. This means that even after you remove all the screws, the cover will not release. Be careful and confirm that it is just catching in the areas between the three sets of keys. They will probably break and I couldn't figure out a way to avoid it but it isn't critical and won't affect the reassembled keyboard. Just be aware of this and be aware of this.

** The power switch and the windows-key-disable switch are extremely delicate and easy to break. The switch itself is tiny and has a miniscule sliding arm sticking out that fits into the much-larger case switch cover.

to be continued because of dumb character limit. (I'm just trying to help here!)

* If you look carefully at the pictures of the solder points, you'll notice that there are two different orientations. If you, like me, want to cannibalise an unused key (such as one of the G1-6 keys or the three near-useless Print Screen, Scroll Lock, and Pause buttons, care a careful look at the broken key to see which orientation you need.

* The keycaps themselves are not that well-designed and become loose after repeated removal, no matter how careful you are. This means that if you like to vacuum your keyboard or shake out the lint, you may be in for a bit of annoyance.

* The shift and enter keys do not have adequate lateral support and you may find that, over time, they become misaligned with their adjacent keys. I think the takeaway message is to avoid Romer keys; they are just not as well-built or designed as Cherry.
