Please correct me if I'm wrong, but to me it looks like the Pi does
not actually fit into the small Schiit case, at least not length-wise. The Pi
might be the same length (edge of board to edge of I/O sockets) as the Schiit case's outside dimension's depth, but it looks to me as Pi might just about be one to two millimeter (about 40 to 80 thou) too long to fit
inside the case.
Could be a perspective thing with the photos, but seems like it wouldn't quite fit.
(Don't have a Pi at hand to check this myself. I've always been more of an Arduino guy.
)
Mounting Pi rotated by 90º would fit, but then you have to deal with the existing on-board ports somehow.
Making a slightly larger case would neither be feasible for what this is, either. That would also mean that it wouldn't stack as well as intended, which would kind of defeat the whole appeal for such a case to begin with.
Using a Modius-sized case would allow for more flexibility and expandability, but it's probably not the form factor that most who use Pi streamers would look for, I am assuming.
Oh, and if anyone wants to go the Sys route and home-brew something themselves; make sure to add vent holes to the bottom or sides, and to the top. Pi doesn't get super hot, but these little cases are sealed better than one might think, so a little bit of air flow can't hurt.
