a series of 2-3 case designs will be available in January for free download of the STL design files if you choose to print it yourself.
however, cases will be available purchase as well after the Kickstarter end.
You'll be able to add it on when we send the final survey.
Thanks.

Johnson,
It would be useful to have a bit more information about the Pine A64+ board dimensions.
In addition to the basic board outline dimensions (see
http://wiki.pine64.org/images/7/74/Pine6...ension.JPG),
it would be useful to know something more about the mounting hole specifications. For example,
• MH-center-to-MH-center dimension (horizontal and vertical)
• board-edge-to-MH-center dimension (horizontal and vertical)
• mounting hole diameter (what size bolts)
• mounting hole keepout diameter (what size nuts and standoffs)
• mounting hole solder mask diameter
It looks like the mounting holes are plated-through-holes. There is an argument to be made for non-PTH mounting holes so that (1) threaded mounting hardware doesn't tear the PTH leaving little metal bits to short out the board and (2) relying on mounting PTH for grounding often leads to flaky behavior if the mounting hardware tears up the PTH. My preference would be for a non-PTH mounting hole, keepout applied to all layers (including internal ground plane), solder mask up to the mounting hole, and marking the keepout boundary on the silkscreen layer.
