I have a 10 year old laptop of very low specs. I had given a detailed description of the specs and made a post regarding the use to which it can be put, and more or less everyone pointed to self hosting.
Now, if the machine is powerful enough, why not put it to some productive use ??
And so l’m exploring an unknown territory.

For me, the best place to start was with services that replace cloud products. Setting up Immich for photo storage, Jellyfin for movies and shows, or navidrome for music.
Isn’t it too little for films ?
It really depends. I’d suspect if it cannot play a video, then it wouldn’t be able to serve it either. People are doing a lot more than this on Raspberry Pis.
pretty much anything can serve files… would probably need to be on a wired lan connection, not slow wifi, and there obviously wouldn’t be any real-time transcoding available as there are no hardware encoders on that chip. it does have decoders to playback mpeg2, wmv9 and h264, though. i’ve used a llano chip for a playback device hooked up to my tv for years–while also running a dietpi in a vm (serves as that tv’s internet source and pihole)
