Also, many Doepfer modules are fairly deep so make sure your rack is deep enough to accommodate them. I was interested in the A154/A155 combination, but my rack could not accommodate the depth of the A154.
Mm... In principle, I know there will be some potential which I will not be able to get. But I think that is part of my own process of learning... I like to think about the usage while I have the things in front of me... Im more a guy who understands things when I see them (and turn knobs with an oscilloscope in front of me) :)

I mean physically deep, as in inches/millimeters. Some racks are shallow in depth and cannot accommodate the physical dimensions of an 80mm modules (the A154 sequencer controller, for example). If you are building your own rack, give yourself enough space between the rails and the power headers to fit some of the deeper Doepfer modules.
