Decent start, I think...but be very careful about module depths with the Moog skiffs. They aren't exactly symmetrical, bottom-wise, and that can restrict the possible choices of modules. Best rule of thumb with those is to stay under 35mm depth (I think you get 40 or so, maximum, in practical terms). Alternately, consider going to a different housing and use the Moogs in a double-tier configuration alongside.

As for the Korg, the only direct interconnection options you have with the modular is via the SYNC ports, which use a positive 'click' sync. This isn't exactly the same as what the Moogs use, which is a positive-going 5V pulse. However, they might still sync nicely via this, given that the threshold value for the Moogs is 3.2V and they react (according to the docs) to anything in that range having a 1msec leading edge. Still, it may make more sense to sync via MIDI clock between the Korg and Moogs, and then use the Moogs to 'translate' trigger/gate functions for the rest of the Eurorack modules. The Korg would also make for a better controller overall, instead of the M32's 'chiclet' keys.
