I could see using a Sys - IV for stations that are 'set up ' ready to go. Open front or lift out, plug in and work. For soldering or dremel etc . A supplemental work light could even be in place. The primary tool in the holder. If multiple things needed to be plugged in, a small outlet strip or multi plug deal could be all set with everything plugged in, just plug in the station.
What other things could a set up like this be good for... model building, air brush?
I think to use Systainers in the current configuration , the lift out would be the way to go. Make the from into a fold down would probably weaken the structure and latching too much.
