Where can I get...?

It's best if you can find out which specific phone you have, rather than looking for a "Note 3 clone" case. There's a possibility that one exists out there.

With my S7589, I considered modifying a generic case by gluing the phone's extra back cover in there. I never followed through -- partially because I'm lazy, partially because I didn't really want the extra bulk of a case, and partially because I knew deep down inside that it was probably a bad idea.

That's the problem - I can't identify the specific manufacturer and model. All I have to go on is the "N3" written on a label inside the phone. All of the usual things, like using a system info tool to find the manufacturer string haven't worked. I know it's not a typical clone (e.g. Star U9000) because it's slightly bigger but that's all. The specs are the same (1Gb RAM, quad core, 5.7" screen, etc.) but it's just those few millimetres bigger. It's really frustrating! Another frustrating thing is that there are lots of similar sized phones available but even when I search for cases that will fit them, nothing turns up.

Like you, I also toyed with the idea of modifying a different case but I'm not very practical and I'm incredibly lazy.
