I'm pretty sure dual 120 AIO is in the < 5% minority. Experimenting with a more common setup is better worth your budget.
For example ... acrylic / tempered glass side panel? That'll get a lot of attention.
Now that the tempered glass came up again we got a little urge, but this will not be ready to the kickstarter and will take more time to complete than we have. Have you seen the concept renderings we have done with the glass sides?
