Sorry if this has been asked before, but I couldn't find a thread answering this. has anyone bought the 4x2x2 enclosure from dubiaroaches.com with the 3sided background (either ledge or regular)? and if so, do the sides obstruct the cable holes that are on the enclosure? it looks really cool and i know my Mu would love climbing on it but i want to be prepared to change the set up if i end up purchasing it. or maybe should just go with the back only and not the sides?
