Okay, the result is.. not quite cool. Uhm. Sorry, won't show off. So, uh, where should I buy the caps then? Now I need at least one new one.. I looked into WASD, also mailed them, but they said that their keys are taller than the Cherry G80-3000 ones. Also, their space bar is "centered" on the bottom (I hope you know what I mean), and the Cherry one isn't. And their caps lock keys are not stepped, therefore not compatible either.
I could stick to these keys, although the scroll lock one now does look.. pretty bad.
