I have a similar setup myself. I use basically an older PC running Proxmox + openmediavault as my NAS (and a bunch of other things, including Plex). I currently have an NVidia Shield and 'Chromecast with Google TV' as clients, as well as a couple phones and tablets. It is pretty hands-off and my family can all use it just fine. I'm content to replace the relatively cheap client boxes every few years. That said, I think I've had the Shield for over 5 years now and other than the original remote being bent in half (likely a jumping-on-the-couch-related failure) it's still going strong.
