The PP layout being where it is allows the DVI shield, or any other shield with connectors at that end, to poke through the ATX connector window to the outside world. The other "internal PP", yes it could move anywhere, and probably will.
So far it's all through hole - the Wiz820io has 0.1" header pins and smt 5200 onboard, likewise for the V2DIP2 with vnc2 onboard. All the stacking connectors, and the ATX power connector are all through hole. If I need to do any volume it can be wave soldered on a friend's wave solder machine. The SMT pads correspond to advanced optional features such as C3 style memory, micro SD, or FT232RL, and can be covered with kapton tape during the wave soldering.
That PP design is a single sided "block" that exists as a separate PCB. So I'm just plonking down the block. It looks like we might get away with a single sided board, which makes running a proto with dry transfer film, or Kinsten photo pcb a possibility. I have some 300x450mm Kinsten here.
Just one other thought for you (because I'm thinking about a similar thing...)
I was going to go with the V2DIP-32 also, because it's a lot smaller. But now, I'm greedy and am thinking about
V2DIP-64 so that I can use the 8-bit FIFO and but that on the same 8-bit bus as my DVI Graphics board...
But, maybe you can do 8-bit FIFO with V2DIP-32 too, don't know for sure. But the webcam example only uses the 64-pin VNC2 chip.
On the other hand the V2DIP2-64 is really, really big...

I would just shoot their support department an email. Should be easy for them to answer.
My guess is that Async FIFO is possible with the -32 - it needs 12 gpio pins which you (just) have. In the table on the datasheet their FIFO example has 8 data + 5 control bits, its the Fifo_OE (output enable) that would get the cut - not sure if this matters.
@ cluso, not losing me just yet, there is considerable assembly required!
