I think the last rack is much better at least in the first instance although it is still (virtually) unplayable... and imnsho - there are still way too many sound sources, not enough sound modifiers or modulation sources and definitely no where near enough utilities...
this is partly due to layout... the sequencers are in places where they will be obscured by cables, so difficult to access, and the magneto, is as far away from what I imagine to be your end of chain mixer as possible - so unneccessarily long cable runs for no benefit whatsoever!!!
I'd rather have this in 2, 6u racks - for reasons of ergonomics... one near vertical primarily for voices, processing and modulation and one in front of it near horizontal for control, sequencing and mixing... for this I'd chhoose mantis cases as they can be fixed in this position...
there are also functions that are missing - which are needed to facilitate the usage of the synth...
how are you going to split the output of the sequencers to the sound sources? please explain...
also submixing voices before processing with filters and delays/reverbs before end of chain mixing is a very good idea!!
why only a single filter? you have a lot more voices than that (I kind of count 7) - I'd realistically want at least 5 or 6: assuming the pulsar generators are going to be kind of used as drones (not enough envelope generators) then one each for those, one for the sampler, at least one for the drum kit, one for the plasma voices and one for the sinc legios...
whilst I'm a big fan of the magneto - I have one and love it - I think it's not a good fit for a rack this size, especially with so many voices in it... you need the space for other modules... the same could be said of both the plasma voices & pulsar generators... slightly smaller modules that do similar things are undoubtedly available... and would free up space considerably...
why 4 sinc legios??? I'd expect that 2 would realistically be enough for a single bass voice - either slightly detuned or in combination with the warps clone... please explain your intended usage of 4 identical sound sources for a single bass voice, with no filter... reducing these from 4 to 2 would free up a lot of needed space...
to a large extent the rack still demonstrates a fundamental lack of understanding of modular synthesis and in particular patching modular synths - which is to be expected from a newbie... but arguing about how you know better with people who almost definitely have significantly more knowledge and experience of modular than you isn't exaclty charming is it??? at least som eof the people helping would, if modular synth forums were academic bodies, hold doctorates, based on the amount of research, practice and deep thought they have excerted on the subject, whilst you are effectively applying to an associates degree...
this almost always ends with people coming back and saying they should have listened!!!
maybe eat some humble pie!!
remember we are trying to help you... something that you have asked us to do & that we are doing freely!!!
plus the rack appears to be 85hp not 84hp... dfficult - the top row won't fit in 84hp... so maths/spatial awareness isn't a core skill either...

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