Premium Pink & White Official Raspberry Pi 4 CaseThe case is divided into five sections, allowing you to snap in sides or tops depending on how you intend to use your Pi. There's an impressive pink top with a cut out in the centre for more flexibility if you want a GPIO cable coming out of the top or want to add a hat. If you don't want to see your Pi, there's a white lid that conveniently fills the gap. Using this with HATs is possible, but it can be tricky. You can probably just plug it in and use
