Cirrus7 is expensive because you are paying for a very high quality machined chassis & case that act as a massive fanless heatsink. Those alone are pretty costly. The price cannot be compared with cheap NUC clones and mini PCs, nor with Apple.
I am not endorsing any particular brand, but Cirrus7 is not that expensive within the fanless market and the quality of the entire build is very high. They also somtimes offer nice discounts for students and SMEs. There are quite a few comparable brands and also DIY options with cases from Streacom or Akasa. If you want something cheaper, Minix is pretty inexpensive, especially when you take into consideration they offer a decent fanless enclosure.
The higher end configs seem fine even if a bit pricy (still, though the Mac Mini seems like great value if you're fine with the OS situation and non upgradable memory).
I still find it weird/confusing why would a reasonably high-end brand be selling configs with such horrible CPUs (especially perf/watt considering the whole fanless thing).
But I suppose they hardly have any options if they want a socketed MB. Laptop chips would probably be a lot better value (both cost and heat wise) but then it's no longer modular and e.g. Lunar Lake doesn't(?) even support non soldered-memory...
That is a good question. They sell those CPUs to industrial clients. Note cases can be configured to be completely sealed for high-dust environments, and it is also possible to get industrial motherboards with connections that no regular user needs. The fanless market has a pretty good niche in factory deployments. There, lots of software is designed to run 24/7 on cheap CPUs.
Mac Minis, and in general most Apple products, tend to offer great value in the lowest configuration. But upgrades are expensive. It is a bit of the opposite situation. I have not used Macs for very long, and I prefer Linux, yet the cheapest Mini looks quite appealing. When Intel Core 2 CPUs entered the laptop market, it was a similar situation. The cheapest MacBooks offered really great value compared to competition.
