So would this be a good /cheaper way of having a nas server? I was using a usb hdd plugged into my bt router to serve music/backup and serve photos but for some random reason it stopped working despit the hdd being fine on a laptop.
They don’t make great NAS servers to be honest. USB port is fairly slow, think it shares bandwidth with the SD card or something. Also ethernet port is only 100Mbps. It’s not fast enough to stream HD video from anyway, but music and photos would probably be ok.
As for setting it up, you’ll have to follow a guide / edit files yourself from a Linux command line. Here’s a guide:

I don’t use mine as a NAS. It’s my VPN end-point and also does backup duties from a NAS to the cloud.
