Doepfer

Hi, I am new to modular but I grew up from the Arp era.

How can I calculate the amount of space a system will need?

I welcome case suggestions.  

The system would have to fit into a home office.

Are the Doepfer cases a little expensive or are they good value?

Are there any cases that a a little more like furniture on the out side?

Are there any plans I can down load?

Thanks for your suggestions
