The case just holds the propellant. It would explode without the cylinder/chamber.
Actually, it would not.
Ignite the primer in an unsupported case and once the pressure inside the case reaches the level to overcome the friction between the bullet and the case wall (which, ignoring some effects of dynamic friction, is the same pressure required to seat the bullet in the first place so you know it's not very high), the bullet would pop out and relieve the pressure.
To get an unsupported case to explode, you have to restrain the bullet's movement when you ignite the primer.

Had ONE 45 ACP with 3.5 Bullseye go off in the press. No restrictions, no die in that station. Case Blew apart. Left sideways imprint of bullet in ceiling. Just a small dent showing lube grooves. Case looked like a peeled banana.
