Many, many options out there, just wondering what you use and how happy you are:
a) DLNA software (or similar)
b) To share a drive (or more) over the LAN
We have a few Pis which are for the kids.
Just got a new 4GB Pi 4 (8GB ones just out, but little availability) on an Amazon deal from yesterday which had some little extras that I’d have to get separately including more beefy PSU, basic case/fan and microHDMI to HDMI cables as the Pi 4 has 2 microHDMI outputs.
I’m sure one of the older Pi’s would suffice, but hopefully gigabit ethernet and a bit more power will help.
