Well, it can be placed inside, above the µSD/SIM card if we leave off the Mini-USB plug like shown in this photo: But then it is difficult to connect it to the internal 5V power (although not impossible - needs to fiddle two wires through the case). And the antenna wires must somehow be connected/glued to the battery cover. This all makes it much more difficult to open and access SIM/µSD or open the whole device for other mods. Not to forget that there is risk to rupture the cables. Another thing to be considered is that the receiver chip might get warm and should not be too close to the battery. So exposing it externally seems to be a good compromise for opening the GTA04. It should only be sealed by some glue or a 3D printed "bump" so that it is not possible to make a short circuit :) What I have as an idea for a next generation version is to add an (optional) µUSB socket so that it also can also be used as a Mini-to-Micro-USB adapter (there is a currently unused power switch in the chip).
