Sorry, I misread your e-mail yesterday - I thought you're asking why
we don't use a case _with_ a fan.

The only issue with passive cooling is that we need to make a good
contact between UmTRX and a case. And this requires careful selection
of a proper case and design of mounting. Again - if you or someone
else want to take on this task - we'd be happy use it.
