Presumably it's been relegated to 'we used to do that' status; many things
are in the 'it seemed like a good idea at time' category.  Generally
speaking if you're having trouble getting a design built, then perhaps the
design is wrong.  As before, that's the question that needs to asked.

You may have a good reason for having the backplane on the top rather than,
well, at the back like most people do it, is it really needed?

I don't see why the power connector has to be at the bottom, how does that
get hooked up?  Why isn't it with the data pins?  Look at IDE hard drives,
the 3.5" ones have separate power & data, but 2" ones don't.  Either way,
both connectors are together, and SATA is the same.  If current capacity is
a problem them just dedicate more pins to power.
