This is Geekworm design metal case is '''only for the Orange Pi 4B, not for Orange Pi 4'''. Please You can refer to [[N400]] if you want a metal case for Orange Pi 4; It reserves all the interfaces of the orange pi 4 motherboard, supports the cooling fan, supports the extraction of the GPIO cable, and also reserves 2 antenna holes for you to replace the antenna that comes with the motherboard. I can't understand why the naming of orange pi is so confusing. . . .
