So for the no fixed IP, I recommend you use some dynamic DNS service... 
I use https://www.noip.com/ which gives you 3 free addresses (you have 
to renew them manually by clicking on a few links on their page, every 
month, but that's a process that takes about 20 seconds). It's 
integrated in some routers (my TP-Link MR600 directly uses it) but can 
also be driven by other platforms.

For the NAS. Depends really on the kind of reliability you want. I'm a 
fan of Synology. They are running Linux. You can configure a 2 disk RAID 
mirror that will ensure that if a disk dies, you have time to replace it 
before you lose data. Their support is spotless. Depending on the 
version of Synology DSM (the name of their OS) you can either install 
SVN server natively (DSM 6.x) or in a docker container (DSM 7.x). I 
don't know why they stopped supporting the native package. But many 
things work out of the box as docker containers on that platform. They 
also support disk hot swap... and even having a hot spare if you have a 
device with more than 2 slots. They are very versatile, and in general 
very good for the money.

Of course building your own NAS will work. Power consumption of an off 
the shelf machine might be a bit higher (unless you get some very low 
power device). Ubuntu has all the software stack to do that. Make sure 
your hard disk / SSD controller supports hot plug (to replace disks that 
fail without having to stop the system). Some people prefer the DIY 
approach. :)

As you can guess, I use a Synology NAS, which I access from Linux, 
Android, Windows machines and even media players throughout the house, 
and remotely as well.
