The semi modulars usually have some sort of side panels which are detachable. For the Neutron I timbered some fitting panels out of beech wood and screwed it on top of my rack. Saves precious rackspace and you can still patch it as if it were in the rack.

That looks really nice. I was at a show recently when an artist was using the Neutron. It sounded incredible outof the PA.
