I'm a little concerned about a few of the pots, e.g. top center back. Not enough room to get a 2nd pot in or out, and if foamed in-place and it ever had to be removed, relocated, or replaced (for whatever), it might involve some major surgery on the enclosure. Looks like transplanting something out & something else in might also be a pain.
Just sayin'... thinking ahead, planning for contingencies, etc. Better to move a few now than after they're foamed in-place.

But it's up to you; I tend to overthink at times.
