sooner or later you will almost definitely need more room - there will be somehtiing you want to do can't patch it with what you have and then find the module you need only to find it's 20+hp and you don't want to sacrifice anything = new case time always try to buy bigger than you think you need - same goes for vcas and mixer channels as far as I am concerned!
I think you have a lot of modulation in this case already - I'd go for something else - possibly fx aid - but I'd want to see if I could free an extra 2hp for the xl version - ergonomics and more modulation points are really useful

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