Maths is way more than 2 LFOs/EGs - it also has a mixer/attenuverter section that is really useful and take a look at the Maths Illustrated Manual for patch ideas
Data takes up quite a bit of space in a small case - I'd go for the tiptop Mantis instead of the Rackbrute - about the same price, but more space and no annoying power input module!!!
Other than that I would add utility modules - the dull polish that makes the shiny modules shine brighter - which are a fundamental part of a modular synthesizer that most newbs forget as they don't understand how to patch yet so fill their cases with expensive modules

I know that Maths offers more versatility - I was just referencing 2 vs 4 in terms of cost per LFO/EG, if that makes sense?
I placed the Data in the rack but it's something that I would only intend to get much further down the line.
I like the design of the Rackbrute and can get it £70 cheaper than the Mantis but you make a good point about the extra HP.
What utility modules would you recommend based on what you think my rack is missing? Thanks in advance!
