I don't see why people are so attached to the pi when much more capable computers - 2013/14 era used Intel NUCs or Mac Minis - are available for a hundred bucks on ebay. Maybe lots of people are using the pi for low-power-draw projects but if people are running a pihole and other services on them you might as well go for the other option.

There's also the QUARTZ64 boards from Pine64 which are definitely available and include fun things like a neural processor: https://pine64.com/product-category/quartz64/
