Any open source host solution for private users?

Situation: we live in europe, there's PRISM and Privacy Shield and all that, to which selfhosting is the solution. Now, my sister, mostly on removed, got concerned with all the hacks and privacy violations over the years. She's a tech noob, so i can't really recommend her prism-break.org

There's a bunch of hosted solutions geared towards small to medium business, like Univention Corporate Server, NethServer, etc.

Are there similiar bundles for private use, basically removed cloud alternative? With services like cloud storage, cloud office, media share, maybe chat, videocall?

Or should i let her wait until i got my box up, VPN her over? I'm only semi-professional tho.
