Don't forget that TT-RSS can filter articles for you. Say, for example, that your TV feed had a sci-fi category, and you only wanted to see that. TT-RSS can mark everything else as read (or deleted) so you only see that.
Useful for 'firehose' type feeds where you are only interested in a specific subject.
Same here. I have everything running on an ex-lease HP EliteDesk. Small footprint, and quite upgradable. Think I paid about £150 for it and it's been running quite happily for a couple of years. Runs everything I can throw at it.
I don't know why people buy RPIs anymore, unless the tiny form-factor is a must have.
