Sorry for the delay, just a quick answer for the few points addressed to me before my next post:
No idea either for “people” in general, but in my case I can just say that it started with the novelty of the Raspberry and it’s futur friends, I wanted to learn of to server, it was cheap, the annual electric cost was less than even the smallest OVH VPS and the arrival, at the time, of the Cubieboard 2 and it’s appealing SATA port instead of just an OS on SD made me go for it. And since I want to spread it’s usage around my friends with time, the cheapest it is, the easier it is to sell them to try the idea too.
Since my collection have the Cubeboard 2, the RPI1B, the RPI3B, and my latest acquisition was the XU4 that run as a home server while the 3 others are collecting dust/used more casually for now.
It’s mostly for accessing my local home network from outside (using the printer, managing the router if I open a new service on the server (i.e. I’m still working on imaps via let’s encrypt), etc…)
Currently nothing much, I don’t think I even reach 5Go, it’s mostly pdf, documentation, sources and ressources for programming project (+ all the git files that goes with). In size it’s almost nothing, but it’s hundreds to thousands of small files with size between a few bytes to some kilobytes.
It’s the case and everything work well for now, but having a list of options and understanding why a board is better than another and what to search while going for a server use case is interesting for me, before yesterday I was never thinking about going for a complete server before really needing one because they were too expensive for my needs, but now I start to considering things like the Asrock Beebox (fanless by default ) or the Intel NUC as a next step, even if it’s not for now yet.
