Okay, your SSA boards need to host what, 10 drives?

that's :

tx+, tx-, rx+, rx-, 8 ID pins, what, 8 power pins? 2 for activity LED, what 
else?  that looks like about 20 per connector + discrete components, maybe 
40+ the interconnects to whatever the backplane boards connect to?

Okay, maybe 300 per board at the most...  I've done more wire-wrap than that 
on one board...

I don't think it'll be that difficult.  all I need is the physical layout 
parameters for the board and time to lay out the traces so that they're all 
the right length (signal) or width (power).
