Junction above cabinets, behind moulding, above removable puck light?

This question is mostly about NEC requirements for the junction. I can put the transformers for the upper display cabinet lights in the cabinet above the oven, but I would have some pretty long wire runs on the secondary low voltage side of the transformers. Or I could put these tiny Lightech LET-60 transformers directly above the puck lights that go into the upper display cabinet ceilings. The transformers would then only be accessible by removing the recessed puck lights that are held in with tension clips (probably not as easy as if it were held in the hole with screws). There is a 2" space between the room ceiling and this upper display cabinet ceiling. Is it acceptable to make 120V junctions in this space, given that it is accessible by prying open the recessed puck lights? If not, I'll just put them in the cabinet above the oven and have long secondary wire runs.

 

I would put them in the cabinet above the oven. Even though you could get to them if they were above the cabinet, no one would think to look there unless directions were left in the open somewhere. It also sounds like the lights and/or their mounts might be damaged with much in-and-out. Not to mention the interior of the cabinet.

 

Indeed, I was thinking the same thing - how would anyone else know where they are hidden.
