ModularGrid Rack

So, after some years of playing with Reason and its rack, I decided a few years ago that I wanted to do the same in a more physical way. Daws are cool, but I'm not really into recording, arranging, and saving my music for later, it's more of a "get lost in the moment" kind of therapy if you know what I mean? I mainly get lost in minimal house/techno territory, so that is my aim. So I started collecting some modules as I found good used deals on the local online marketplace. I figured I could buy myself a 104hp case when I had enough for a start. I mean, 104hp gotta last forever?? oh well...

So with the current collection as above, what would your advice be for the future be? I am quite good at tinkering and know my way with a soldering iron, but not so with SMD's yet. My wishlist consists of effects, O&C, Pams WO, and someday a Befaco mixer.

It would be interesting to hear your thoughts!
Thank you!
