Using this Flirc aluminum case for your Raspberry Pi 4 is a breeze. First, place your Raspberry Pi 4 into the case. The design allows easy access to the GPIO pins through the slot at the bottom, so you can connect your devices without any hassle. And when it comes to accessing the SD card, you don't need to disassemble the case. Just reach in and you're good to go. As for maintenance, since the top and bottom are made of soft silicone, a simple wipe with a damp cloth will keep it clean. The ventilation slots at the bottom are important for keeping your Raspberry Pi cool, so make sure they're not blocked. Remember, this case doesn't come with the Raspberry Pi 4 computer, so you'll need to provide that on your own. Also, check out our other aluminum cases for Pi 4 that come with or without fans if you need different cooling options.
