Modding Tech21 Ritchie Fly

[stompbox steve]

Hello I would love to build my own remote switching system or multi-effects unit but I dont have the time or the know how to easily / succussfully pull it off.  I thought about rehousing a handful of pedals and hard wire, but I was thinking of getting one of the Tech 21 multi effect units )Ritchie kotzen Fly RK5) and see about adding a couple more effects.

Does anyone know what it looks like inside?  Is it one board? Or individually units to squeeze things in?

Looking to add a small flanger (overseas model)and a nano bassballs. I know I might have to move switches,etc  But at least the heavy lifting was done. 

Your thoughts?
Thanks Steve
