I would also not recommend anyone to do the same. For one reason or another, this thing is there. Any changes in the responsibility of the person doing this.Removing that internal cover may also lead to those components failing sooner. Since the CDM has been discontinued for some time, just keep in mind that if anything fails on the board, you might not be able to get it fixed. Generally if something has been soldered on, it isn't meant to be removed.
But still. I'm not sure, but it seems to me that the CDM Limited Edition, which has a perforated shell without a window, does not have this cover. Obviously, it has a slightly different thermoregulation. And yet, it is the same device. And it works good without a cover.
