It's a 4U panel, so 7.5" wide (and completely stuffed, as shown).  This is a
dual multimode filter with three inputs per filter, and all six modes
available separately on every input.  There are six ICs: one V2164 and five
TL074s.  This is my second most elaborate PCB.  There is a VCQ daughterboard
for this filter as well which I chose not to install on this build.

Um...  If the layout is tight, then you should be OK, because you can make
the board as deep as you want.  However, it would seem to me that the panel
required to control all the features of a PCB with 40+ ICs would have to be
so large that you could fit just about any PCB behind it.  What is this
behemoth, anyway?
