The case is probably best. But such a pain. And you can't survey your harem if they are all hiding.
I have a hanger on the wall with just the white plastic things, the kind that screw in first. You have to be careful not to let the white anchor break the surface of the drywall. But I have it holding my PRS CE 24, my 2nd best guitar, at least $$ wise.
As far as things hanging sideways. I used to fly airplanes and another pilot once told of the time he was in Texas. he said in Texas it was always windy, real windy. He said one morning he woke up and looked outside and the flag was hanging limp. he suspected maybe the wind had stopped? That was supported by the fact that all the cattle in the field next to the airport had fallen over on their sides. But when he looked at the windsock it was straight out like normal. They had long since replaced the normal windsock with a piece of logging chain, which worked much better in Texas winds. But here the windsock was straight out? So he went out to investigate and he found that the logging chain had rusted solid in the sideways position!
