that looks about tight. You do not need the S/PDIF transceiver module for the Buffalo. It accepts S/PDIF directly.
You can wire the output of the volume pot to each of the DACs and control then both at the same time, as long as both board share a digital ground.
Sorry if this should be obvious, but pls can you confirm if the input accepts I2S and DSD data streams. Presumably it detects DSD and processes accordingly. This is how I understand the input spec, but could be wrong.
An external switch (Otto) is only for if you want to connect 2 x devices. DSD and I2S from the same device will be processed OK.
Thanks,

I use regular wire if the distance is short (twisted if you can).
If you are using AES/EBU, you should use an XLR for the balanced signal.
Yes, either DSD or I2S can be connected directly. If you want both, or two of either, use an OTTO to switch them.
Yes...
This can work with the B-II, and the B-III when it is set up to mimic the B-II in the input mapping. I would assume that the B-IIISE is set up like the B-II for the inputs, in which case it will work on the same pins with I2S or DSD data. For correct mapping your source needs to be this way:
bit clock=bit clock DSD
word clock=data left DSD
data=data right DSD
masterclock=masterclock (if used)
ground=ground
The only other concern is whether you wish to chnage the IIR filter setting for DSD vs PCM plaback, but it is not necessary.
I have tested this using a B-III set up the B-II way, and it works fine with multiplexed DSD/I2S signals on the same input pins as above. The good thing with this approach is that it avoids any switches in the data path, my experience is that even the best switches can degrade the data stream somewhat and affect sonics.

Would be cool to show the layout with all the connectors. I'm thinking about the integration in the box and I don't know which switches/leds I'll put on my front panel. Is the layout really similar to the Buffalo3 version ? PDF doc wanted 
Also, I'd like to know if one input is master and the other one is slave (between TTL and I2S)? Perhaps I won't need a input selection switch...

Yeap, it works perfectly with the Amanero board. Other boards like the EXA use the same signal arrangement so will work too.
