Jeff - thx will take your advice on the caps - Easy change now on the MMM as you can pull the leads off - I debated about creating just a pocket but decided to create enough room I'd have to got through most of the case anyway.
I was in two minds about the fan too as it means an extra y splitter - not the end of the world... I'll go for V3 tonight... I also have 3 MMM's to do this to...
Caps charge almost instantly so no issue for MMM - Extra caps help with any Ripple Current and I've generally found to help the ESC a lot.
PS here are the caps:
