I have two Rasp Pi Zero’s stuck behind my TV that cost me £10+£10 DVB HAT’s x 2 (before the COVID scalpers took effect) as a poor mans Homerun server that have plenty of storage - be that a new USB drive stuck in them or even using my NAS with NFS for storage.

Device cost/viability isn’t a thing here.

It’s getting people signing up to a service that’ll be plastered with adverts every 15 mins? I wouldn’t touch it with a barge pole.
