This is the first affordable Raspberry Pi case made out of aluminum. We wanted to ensure we didn’t sacrifice form over function, so we used the aluminum housing of the case to provide a built in heat sink.
Really a beautiful well made case. If you are using your Pi without needing access to the I/O pins this is a great way to go. I would have wanted an edge connector as part of the case if I needed to put I/O cables on an off a lot.
