How would you like us to evaluate your rack? The current state of the picture or functionality without the semi-modular synths you've mentioned (Neutron, MiniBrute, 0-Coast)?
If you're dependent on your semi-modulars then anything in the rack is a bonus. As a self-contained rack, there are a lot of holes or things I'd be concerned about if it was given to me to use without the semi-modulars.
If your plan is to ditch the Brute, then having a Rack-Brute case may not be the best option for your modules. You've already bought it so we're stuck with it... unless you really like the format. Again... where should we be aiming?
