the rackbrute case does not have 1u and the power supply is not sold separately...
better to put the 1u modules in the 1u rail than in an adapter - so you have more space for 3u - just move the disting ex to be near the bigger screen, but I'd only buy that if you need it...
racking semis is a waste of rack space and power...
too many small modules too close together... you are trying to do too much in too small a space... bigger case and bigger modules or just fewer bigger modules - the shitty ergonomics of so many 2hp modules and trimmers instead of pots will make it unplayable... remember 1hp = 1/5" (4.08mm)
do some research on the guy behind synthrotek before buying their modules...
why do you think you need 2 noise sources?
why are there no vcas?
how are you mixing - the deluge, minibrute 2s, the output of the rackbrute6u and the o coast?
take a look at the hints in my signature and spend a considerable time thinking about them... they are a guide to getting the most versatile modular for the least cash...

Utility modules are the dull polish that makes the shiny modules actually shine!!!
sound sources < sound modifiers < modulation sources < utilities
