how about some screw holes for secure mounting?:) also caps for ic power rails would be nice to be on the pcb. what opamps you plan to use? hmm, i'd like to build this eq at some point.

more ideas to chew on :)
there is very much wiring... is there a possibility to arrange  the i/o pads next to each other? or maybe run io and power "bus" traces at the backend of the pcb so one could use simple jumpers between the pcbs to daisy chain them? in which case you could manufacture one big pcb and have cut lines between modules. one could then use the whole pcb without much wiring, or snap modules apart and use what ever needed;)
 
I added to filter board but not band boards.Easy to add.And to get more room i removed power rail caps.It's easy to place caps under PCB.

Your idea are better but i'm looking for cheap solution.Back board is extra money.Using some wires with molex connector is cheap and easy.

And making too small boards without back board is good for casing.Even you can push them to 500 series.
 
yeah no separate bus board, but trace the buses to the sides of the filter board adjacent to next filter board ;)
 
€30 for mono channel.

1 x FILTER & I/O Board
4xBAND Board

By the way i added front panel design.

This week i will order PCBs.
 
aha! now that i see your frontpanel i understand your decisions. the pcbs are angled to save front pabel real estate :)
 
Boards will be placed angled cause i have to fit stereo unit to 1U case.Boards are really small.IF i put only one unit into 1U,there will be lot of room but not usable.Placing like this is better.
