Gopro Metal Cases?

[Arctic Pride]

Anyone running those metal gopro cases I've seen on flebay and other places? Any issues with them? Heat/fit e/t/c?

I'm needing to come up with a creative solution for mounting the camera on a new lid and these gave me an idea...

They should be way better for heat.

They're nowhere near thick enough for magnets to hold them on though.

Ordered one, definitely meh...already moved onto modding the blackout case and using STRONG magnets, not sure if these will effect the camera at all...
