When thinking about how the plumbing goes from the engine room to the warp nacelles and how much room I need to try and make near the flight deck I decided to build out the engine room.
Of course, the Enterprise went through several versions, so here is the one from the "Naked Time". Still need to do the front and hallways.
I think that those two "big machines" in the middle of the room must be movable by antigravs or something as they seem to be re-arranged alot
