We have to solve the money problem!

I used to run such things on my NAS/Server at home (And I still do, though I'm currently changing some things.) But in addition to the 4.50€ for ~20W of electricity, it was maybe 600€ for the machine, so another 5€ a month over 10 years. And then my internet contract is a bit more expensive because I need an IPv4 address which can do port forwarding... On the flipside, I can just attach a 10TB harddrive and have it available everywhere. And that'd be very expensive with a cloud service or hoster.
