You need way more utilities and half the oscillators. Think Mixers, Logic, Offset, Attenuators/Attenuverters. Also just because eurorack has he same mounting and power requirements doesn't mean that everything will work best with each other, as everything has a different voltage range that it works best in (for instance maths puts out 10v slopes while the 4ms puts out 5 volt slopes.
If you're just starting I'd pick one company to make a system that's AT LEAST a third smaller than what you have.
If you're just starting I'd really spend at least a year with a Make Noise O-Coast and an O-Control (and maybe a really nice delay/reverb pedal) and ONLY think about a full rack after you've mastered those things. You'll have a LOT of fun with that set up.
I speak from experience, your knowledge and research is worth way more than a rack full of reddit favorites that you don't know how to use yet.
