Me personally I am not a fan of putting electronics that have adjustments in a place I cannot readily get to it and make adjustments. I am also concerned of having them back there because of the lack of air circulation and the possibility of overheating which is definitely bad for electronics.
As to whether you move them really goes to the fact that the whole system will have to come apart and the wiring redone to accommodate the move. Do you feel confident to do that kind of work? If you do then I would say go for it. You would then have an intimate knowledge of how your system works and would then be able to troubleshoot any problem you could have in the future. You may even find the elusive "blue USB" .
If not then comes the added expense for hiring a second person to do it and even more money ...which sucks!
