That's getting kind of elaborate, I was hoping for something along
the lines of a repurposed Tupperware container 8-) I'm hoping to
keep the case cheap compared to the Pi and other parts.

Well, maybe not quite that crude. But, a small food stoarge container
with spacers to support the disk and Pi and a few holes for cable access
might come close to what's needed. A fan mounted on a hole in the box
with vents to guide air across the Pi and disk complete the package.
One of the harder problems seems to be making it assemble-able.

It's true that a big passive heatsink avoids a fan, but from what I've
seen a 2.5" disk gets warm when it's busy, with no passive heat sink
practical.  Seems simpler to just use the fan to cool both.

Thanks to everyone for replying, I'll keep thinking for a while yet.
