There are plenty of Mac mini case modification projects on the internet. Though the unibody aluminum housing design had been there for almost a decade, it’s still the best looking mini computer case on the market imo.
In mid 2019, Raspberry Pi receive a huge update - the Pi 4. We finally got true gigabit ethernet, USB3.0 support, and a lot more. This makes Pi 4 suitable for simple NAS project (also for TimeMachine backup). So I decide to build a fake(?) TimeCapsule with Pi (at least the case is real, or should I just call it “Fake Mac mini” ? lol)
