@Mytran - Yep, the tapered version of the power pipes help. Now the limiting factor are the dimensions of the engine room. If it were to go in the primary hull, it can only go in on the inside of the undercut as it is too long and wide to go on the outside of the undercut. I can see it resting somewhere on deck 5 or maybe 6 to keep it close to the energizers.
After watching "The Naked Time" it also seems that something funky is going on in the curved hallway going up to it. But in "The Ultimate Computer" we see another long curved hallway (although different.) I might try to work the differences in as a refit in the engineering section on the primary hull.
