After reading a few comments here, there are lots... May I suggest something, why dont you start with buying what you want, but in segments. That way you can learn while building.
What I have learned from the years I have been into modular is that you might have an idea of what sound sources, filters etc. You like and you are dead set on bringing your idea to life. While that might be cool and all, often it will take many iterations to find out which modules actually have that sound you like, you might even fall in love with the visual aesthetics of a module and expect it to be your dream synth, much like a relationship. The qualities you were looking for when you were 16 might not be what you want at the age of 38. I think you get my point. But by all means do what you like, no one here should tell you what is right or wrong, however I do agree in that you will most likely be overwhelmed, if you imagine patching on a basic level, yes this might be all fine and dandy, but once you dig in, a system like this is first of all unstable and it will take hours and hours to make a deep patch using all the modules. Imagine never to have driven a car before, and someone tells you to turn on the parking lights, not the normal lights. no one would be able to do that before getting used to the controls, and then you find out after 3 years that your car have automatic parking lights.
For me it took 14 years to finish my system, and I sold everything I started with except one module, that was my first VCO, I found that this was actually by pure luck my favorite, I thought that having more stable VCO's would be great, I bought some, nah they sounded like S**T to me, even if they were highly praised here on the forum. Then I thought, yeah well, ok, let me try some digital, maybe that would be cool, nah, not for me. Then I thought, yeah, wavetables is the top, nah... and imagine this going on and on with envelopes, filters, LFO's sequencers, you name it.
I am 99% sure you will not be happy with your system as it is now, in 1 year. new modules enter the marked, and you want to try them out to hear what the fuss is about.
Sadly I can no longer see your rack, but I did see it some days ago.
Do what you want is basically what I am saying, it's a process and you will get there in the end, I think people here is trying to help you avoid the pitfalls we have all fallen into, and wasting your money.
Best of luck
