Before you begin
Enable SSH on the NAS.
If you have a battery backup unit then enable UPS.
Download LibreElec image files for all architectures of Raspberry Pi’s on the network (i.e. RPi1, RPI3)
If your router acts as the DHCP server in your network then it will need to support network booting (most do not) if you want to continue to use it as the DHCP server, otherwise you will need to disable DHCP on your router and setup a DHCP server on your NAS. An alternative is to install a Linux firmware to your router if it’s possible (i.e. OpenWRT, DD-WRT, etc.) which is the scenario used for this guide.
