The M32 doesn't belong in there, either. Consider how much space it takes up in the rack, and how much that space actually costs...then add it to what you paid for it. Put it back in its case as well and get a multi-tier bracket for the Moog stuff...that looks cooler, anyway.
As for the rest of the build...uhhh...OK, it's a bit apparent that you're OVERreliant on the Moogs for things such as VCAs, attenuverters/mixers, and so on. Plus, there's a lot of little 2 and 3 hp modules all over the place in between the "sexy" modules (and we'll get at that in a bit), sort of like shower-grout mold. Or something about as useful as that, because if you'd just return the 120 hp that the Moogs are stealing, you'd have room for PROPER versions of those modules, such as mixers where you can actually control your source levels (kindasorta important). And the layout is just...well, it's haphazard, very random, with no discernable order to the modules with respect to signal flow, function grouping, etc.
There's some decent modules in here...but it doesn't seem like there's any overall plan for this. Even with the Moogs in place, the remainder of the modules just don't seem to make a lot of sense. Then there's the plan to toss the Audio Damage delay...which I think is just plain nuts. For one thing, it's a pretty good dub-style delay...and if you're doing repetitive ambient work (ie: Berlin school type stuff), you NEED delays such as that to increase your sequencing density and to "canonically" shift parts of one line against each other...delay-line hocketing, basically. Plus, it has an INSERT in its feedback loop...which has massive abuse potential! Yes, I see the Chronoblob up above, and yes, it's a delay with that same sort of insert...and actually, it and the DubJr are some of the very few affordable and decently-sized delays that offer this. It's also discontinued...so if you toss it and then realize that that WAS a mistake, good luck finding another one!
"Additions" aren't the problem here. This is a build that's got some real systemic problems, in my opinion. You've got a cab here that's got the size necessary to house a KILLER module complement, but the whole thing's hamstrung by the Moogs. They're robbing over a third of your cab space which you clearly need for actual modules...as you're discovering. This would be MUCH better off if you pulled those and then worked at making a cohesive modular synthesizer build out of the odds and ends that currently occupy the rack. You can even keep some space open (which I'd suggest...3 x 104 SHOULD offer plenty of expansion room) to build beyond that. Then start regrouping modules, aiming for a layout that's way more cohesive that way. Once you do that, it should be considerably more apparent where the shortcomings are.
