My knowledge of aftermarket cases is pretty much nil. What I'm looking for specifically is a case that is flat. The stock case for Anne Pro II is actually on an incline. To a small extent the keycap profile may be responsible a little, but you can clearly see how much of an angle it is on. If I can't find any replacement I may just rig some feet for the bottom half of the board. I prefer plastic casing, but I may have to settle for what is available.
I'm not sure why most people like to flex their wrists while they type (probably because their desk is too high),but it's uncomfortable and unhealthy
