The case comes in five parts so you can snap in sides or tops according to how you're using your Pi.  If you want a GPIO cable coming out of the top or want to add a hat, there's an impressive pink top with a cut-out in the center for more flexibility.  Or, if you're not a fan of seeing your Pi, there's a white lid that conveniently fills in the gap.

This case's smart design and customizability makes it a worthy addition to the Pi case genre!

This product is just the case.  It does not come with Raspberry Pi or components.  It's designed for the Pi 3 but will also work OK with Pi B+ and Pi 2 if you don't mind that the LED light pipes are blocked (the LEDs moved on the Pi 3)
