"commercially manufactured gun case" is basically anything manufactured as a gun case, from a gun sock to a full hard shell rolling case.

Also, expanding on the Homeless question, suppose you become homeless but you still have an automobile and that becomes your "home".  Are you allowed to keep firearms in there because that is your place of residence?

Well, taxicab drivers, even those who own their own cab, aren't allowed to carry a gun, even though it is their place of business and they as boss say it's ok.  Beats me where in the law that's discussed (not HRS 134), but I remember it being in the papers after a cab driver was attacked by his fare abut 3 years back. 

It probably has to do with the law concerning carrying on a highway.

[§134-26]  Carrying or possessing a loaded firearm on a public highway; penalty.  (a)  It shall be unlawful for any person on any public highway to carry on the person, or to have in the person's possession, or to carry in a vehicle any firearm loaded with ammunition; provided that this section shall not apply to any person who has in the person's possession or carries a pistol or revolver in accordance with a license issued as provided in section 134-9.
     (b)  Any vehicle used in the commission of an offense under this section shall be forfeited to the State, subject to the notice and hearing requirements of chapter 712A.
     (c)  Any person violating this section shall be guilty of a class B felony. [L 2006, c 66, pt of §1]

Is it okay to have an empty magazine inside or  must be remove?

Legally, an empty magazine should be fine. 

So is there anything that says where in the car it has to be kept? As long as its "not readily loadable." Say my case doesn't fit in my trunk, can I keep the gun in the back seat and the ammo in the trunk?

No.

While the homeless aren't prohibited from owning guns (as far as I can tell), they are lacking a place to legally possess them.  I don't think that storefronts or park benches count as places of sojourn.  So, while you many not have to get rid of your guns, you certainly could not possess them.  Maybe you could find an affordable storage unit that allowed firearms and store them there indefinitely.  If you had a friend with a home, you could "loan" him your longarms, dropping by every 14 days to renew that loan (and mooch a meal).

However, if you were to find yourself homeless, I'd think that the disposition of your firearms collection would be relatively low in your list of concerns.  Aside from the snubbie that you carried illegally for self-defense, the rest would probably be liquidated for food.

There is one case where the courts affirm that a vehicle, even if you are living in it, is not considered your place of sojourn...can't recall the case references....
