I also have a bunch of SBCs lying around waiting to be used, and also an ODROID HC2 which has been in use for years. I only dislike that it's not powerful enough for encryption--LUKS + samba could not read/write at disk speeds and was unreliable in my testing.
Really wish there would be an upgrade to the HC2 with about three to four times the performance.
