I'd just like to mention that I've changed a HP board of that dirt-common type you get with every office computer nowadays, to the AngleWide(ISO) ergonomic mod (that's the one where you rotate the ZXCVB> keys one step to the left, and the right-hand half-rows one step to the right).
Remapping such a board to Colemak would lead to a bumpy result but this mod preserves all keys on their original rows so it's okay. Furthermore, while it's quite okay for me to type Colemak without visual guidance I do prefer to see the Wide mod because it moves symbol keys and it's also a tad nicer to have the homing bump in the right place again (although that's a minor point).
The keys snap off and come back on just fine, but as is often the case there's a special consideration to take with the J key (I'm not moving F in this mod) because the bump keys are used as an anchor when building the keyboard. There's a tiny plastic ridge in the key cap's chute that fits into a notch on the key cap, so that you cannot place the bump key in any other position nor place any other key in the bump key's position.
This was easily remedied, however. I just scraped off the ridge carefully with one blade of a pair of scissors on the chutes that held the old and new positions for the bump key. The key worked perfectly afterwards, with no slack or anything! Obviously, that notch didn't fulfil any other real purpose than to guide the keyboard montage.
Just don't be a complete brute and cut the membrane below or something - and if you lose the tiny plastic filing into the chute you might want to try and blow it away I guess (it stuck to the scissors so I got it out clean for one chute, and I blew the other one out of the chute when it dropped in).
Happy hacking! :)
