Looking for some feedback on adding to a rack build. The initial modules are based on a rack that appeared in this YouTube video:

I recently purchased the ASM Hydrasynth and an Arturia Minibrute...looking to dip my toes into modular and thought getting a Rackbrute 3U that could be used with both the Hydrasynth and Minibrute and incorporating the modules used in the video would be a good start. I've created a rack with the corresponding HP (88) for the Rackbrute and will have 19 HP left to add to. Is there anything critical that I'm missing and/or something I should definitely consider adding to the remaining 19?""
