Raspis are cheap and simple. Fewer things to fail, but each part is more likely to fail. They have low cooling and power requirements though. I'd expect the storage to be the thing that fails most often.

The interesting experiment with raspis used in high uptime scenarios is when you make a cluster of them. If you aren't reliant on any one to stay up, then you can afford many more hardware failures than traditional clusters, albeit much less dense. You trade size, performance, and ease of maintenance for systemic reliability. Unfortunately, I can't find the articles that look at this.
