Self hosted Dropbox alternative - a Seafile setup overview

Sounds a good alternative indeed.
I remember that Western Digital had something called "mycloud" on their NAS drives.
I guess the big thing with this will be the requirement to use DDNS if you dont have a static IP address, how about connections over CG-NAT?

Not sure about that, I imagine clients would be ok on CG-NAT, but I can't imagine the server would cope with it.  In fact that must be the case for the client apps as my camera upload works when i'm out and about, the mobile networks are cgnat iirc
