Thank you so much for the feedback!!
I was thinking about actually making a v.2 in the future that was a little wider, and more spaced out!
The hole for the standoff will be in the lower left space! Great idea and thanks for that input 
For this version, I planned to make custom banana cables for the users to purchase 
Something along the lines of these - the 4mm bullets on the top are what will be the banana jacks in the cluster of 5 - and I am working on an idea for super slim banana cable/plug sets
Thats for the noodlebox link!! I will check all of this out
