Dear Johannes,
i hope my idea can help you a bit. I think it might be a good idea to remove your Pacarana from your fixed studio rack and buy a good laptop bag, at least for the beginning.
I don't know if the Tom Bihn Brain Cell bag for the Pacarana is still available but i am sure there is a similar regular laptop bag which fits well.
A Pacarana + power supply a Fireware and a USB cable plus a small USB audio class compliant audio interface (for example the Zoom H1 recorder can be used as an Input/output device) will fit easily into a mid sized laptop bag together with a small modern laptop and you then could take your Kyma setup home whenever you like.
It's really easy and quick to setup, similar to any other outboard hardware device like for example a hardware synthesizer or a hardware controller.
If you don't want to carry around the Studio Pacarana you could buy a 2nd one, maybe a Paca and place the Paca at home.
Later when you dive deeper into Kyma you will recognize that most things are done much faster then in Max because Kyma is in many aspects very different to Max.
Kyma includes very inspiring tools which alow you to come quickly to results on the beginner level as well as the intermediate or expert level. Those tools are easy and quick to learn and where improved with the recently released version Kyma 7.1.
If you are aiming for more complex sounds i can speak from my experience as a long time Max/MSP, CSound,VSIG and Kyma user: athough on the surface they seam to be all very similar there are many differences in the whole process of making your ideas work.
By reading the Kyma X Revealed and Kyma 7 Revealed Books and by studying the old and new forum i improved my whole sound-design skills as well as my musical skills and i changed to a much faster and flexible way for working with sound and musical structures.
Today i am spending more time without a computer "thinking about" and "designing" my sound ideas in my mind or in my "small black book" before i start actually programming the final solution quickly in Kyma.
Very complex structures can be build in minutes in Kyma which would take you in Max hours, days or even weeks because of the different nature of both.
Kyma is an object-orientated sound design language which does all its computations in real-time on a dedicated DSP based computer system. A software programm like MaxMSP is simply a different approach. Both systems have advantages and disadvantages.
Anyway i think it might be helpful to be able to "run" Kyma 7.1 without the attached sound computation engine to explore and learn the Kyma Environment as well as to evaluate simple SmallTalk - (CMD+Y) and CapyTalk code and develop "Tools" without actually compiling and running the final sound.
All the best,
Christian
