Hey, i dont even have any serge stuff at all (i lurk on many
lists for technique though) but i do have a couple of other modulars on skb
pop-up mixer cases.
Appart from the (aproximatly) 5" depth limits, theres also a
problem at the back/top of the case, where there are brackets that hold the case
rack frame when its folded down.
Check Larry's (Stooge) page for some relevent info, better
then i could explain. Your looking for the paragraph that
says
"Cutouts in the back and optional top
allow the case back to just clear the internal tabs so the SKB case can close
with the back attached. "
As i say, i have no serge, but 3 pop up mixer cases, housing
doefper, a.solutions, efm and oakley modules.
These are the only issues that i can guess at.
Cheers, Julian
