   Umm ... that'd be a lot more expensive than just
   cutting/gluing some raw plastic sheets  :-)

   There exists some thin 'expanded aluminum' sheets
   that are normally used on the bottom half of
   screen doors - silver or pretty gold. They are
   easy to cut and bend tight. Look around in
   a Lowes store. I've used that for make-do
   enclosures before.

   If you have one of these :

   then you're way ahead of the game.

   I think of a Pi as "economy" and thus keep the
   apps/add-ons kinda cheap. Otherwise I'd use some
   kind of desktop.

   Alas those cheap BeeLink/BMax units only have
   one SATA port so you can add an SSD drive in
   the bottom of the box. I think Orinco sells
   a "SATA hub" ... kinda like a USB hub ... that
   can turn one into many. Dunno if it only works
   with Winders drivers however .......
