External GPU docks for enhanced mini PC graphics
External GPU docks offer a newer, potentially faster but less standardized connection. Compatibility is highly specific to certain mini PC models, so you must verify that your PC has a compatible OCuLink port. Availability is more limited, so check specialized sites or directly with mini PC manufacturers.
