@frostschutz I tried to take the PCB off but I couldn't remove it fully because I couldn't figure out how to remove the wires connecting the battery to the board (it looks like it's just clipped on but feels soldered). I think I could see cracks along the sides though, corresponding to the diagonal lines under the bezel so the screen probably is damaged.
@JSWolf Yup, that's what I plan to do (get a new H2O with a case this time). This H2O had an amazing battery so hopefully I'll have a good spare to use in the future. I just have to remember to keep this thing charged every once in a while
