Industrial PCs are also commonly passively cooled and more or less sealed, using the case itself as a heatsink and protecting the electronics inside from airborne contaminants. Individual components can also be industrial or automotive grade rather than commercial grade; for example, industrial-grade SSDs are usually rated for 85°C and often have much higher write endurance ratings than client/consumer SSDs, and may also be protected with a conformal coating or epoxy potting across the entire board.
