The SheevaPlug was the OG Raspberry Pi released years before the Raspberry Pi that nobody cared about because there wasn’t a media hype around it.
Now the interesting part is: it included an ARM CPU @ 1.2 GHz and it was released in 2009 with dedicated Gigabit ethernet plus another isolated USB chip. Note that the Raspberry Pi was released years later, in 2012, with a 100M ethernet + USB shared chip that was total garbage. They kept selling that garbage until 2019 with the release of the Raspberry Pi 4 that finally came with Gigabit.
Another interesting fact about the SheevaPlug is that there was a variant with an https://commons.wikimedia.org/wiki/File:SheevaPlug_ports.jpg once again totally obliterating the Raspberry Pi 4 and making it the perfect low power system for a NAS at the time.
