dounedininiI did a little bit of digging regarding replacing the case on the anne pro. According to MechType, "As it stands no aftermarket 60% cases are compatible with the Anne Pro. It has non-standard screw boss placements. Further complicating the issue it requires space to store the internal battery. The only option would be to mod or customize one yourself". Comparing the screw hole layouts for the datamancer case and what the anne pro's stock case, you can see that they're not entirely compatible. Plus, you have to take into account the battery of the anne pro.
