ModularGrid Rack

Hi, this is what I have built in the last 18 months..its been a steep learning curve..(still learning).. its settled in a nifty case.. i have another nifty and am awaiting them shipping the double case rack ears to have two .. one above the other..hoping i can fill it with modules to keep me going for a long while..(famous last words)..I have tended to buy modules where I have watched or read a good review , but with no clear plan.. i realise i need to be more focused.
So.. what to do next ? please feel free to suggest anything.. i know i will be asked quite rightly what do i intend to do ..genre wise..
lets say i am not tied to anything apart from i have a dfam which i like to use my eurorack to compliment rhythmically...hard techno if i am pushed into a genre... i am not neccessarily needing effects right now, as i am enjoying what i can do with the basic waveforms.
cheers everybody
