yes it is
and congratulations on choosing a case that is a decent size!
if you don't already have (all) these modules then:
black pams may be unobtanium - iirc it was a limited edition!
plenty of space = no reason not to buy an original plaits - not only better ergonomics, but Emilie, the original designer, gets paid!
you probably don't need the adsr - unless you are planning on playing with a (cv) keyboard - I'd swap this for a bi-polar lfo - doepfer will do perfectly well
are you planning on sequencing from pams?
how are you planning on listening?
next purchase VCAs - don't skimp - get a quad (veils, perhaps) - you may not think you need them now, but you will - they are just as useful for modulation as for audio

Utility modules are the dull polish that makes the shiny modules actually shine!!!
sound sources < sound modifiers < modulation sources < utilities
