K-Meleon still runs well on older hardware (as well as Opera 12).

The best upgrade for my old x86 hardware seems to be Haiku OS. The browser situation is getting better all the time. As the overall system becomes more stable, even the full-featured non-native QT-based browsers will be more stable as well.

Other thoughts: nextcloud server running a single service (multiple nextcloud services will run like a dog on small hardware).

TinyTinyRSS gateway/server (your own google reader).

Text only usenet caching server via gmane.io and the other servers like sdf.org.

SSH / VPN gateway.

I have the first gen Apple TV and it makes for a great streaming server and networked stereo system.

I run nextcloud on a thin client, but i mist admit it’s not that “thin” actually.

It's the fujitsu esprimo q920 (iirc) and it features a 4th gen core i5 (4c/4t) and 16gb ram. It’s been working fairly well for the last ~3 years.

What software do you run on your Apple TV?
