Hello --
Searched and found occasionally someone will post in re case/enclosure for BeagleBone boards.
Ordered and received an alloy case from Netgate in Austin TX. Designed for BeagleBone Black. It's a nice case.
Anyway, looks like they are getting out of BBB biz and are offering the case for 10.95$, down from 18$. Similar in design to the former Logic Supply case.
Couple notes:
Holes for enclosure fasteners have either some anodizing, or metal, in there. So starting the fastener takes small bit of effort, on first use. Be certain to chase those threads out, so no galls get on the board.
Not shown in the product photos is the bottom, which allows M3 fasteners to mount the enclosure to standoffs or another surface.
They did a favor for me on a custom shipping request, just putting this out there.
