Do you know approximately how much will the case weigh?
Concerning the plate, as you separate ISO and ANSI, does your ANSI plate allow for 1u RShift? I use ANSI but I need that 1 extra key that ISO layout has there.
Do you have a picture for the difference between sandblasted and waterclear? Is sandblasted = frost?
EDIT: No need to answer the last question, I got the answer from the thread. I didn't read it thoroughly enough. But a smoked finished instead of a waterclear acrylic polished finish sounded better as others proposed.
