mldonkey for ed2k/kad network and bittorrent

You still have realvnc lite. It is free, 1 user, 3 machines, less features, but the basics still there.

Well you could run these services in your server (only if you have enough spare bandwidth, ram and cpu) to help the comunity to circumvent censorship in some countries, like Russia or Iran. Here you have more information for tor and i2pd.

Tor relay (guard/middle or bridge/snowflake) and i2p node (i2p, i2p+ or i2pd)

Then samsung galaxy a35.

Samsung phones nowadays are one of the best software support on every budget, starting with the A15 4G (~150€) with 5 years to the flagship, S24 ultra with 7 years.

Samsung galaxy A15 5G, Cheap phone (~180$), micro-sd, headphone jack, good software support (4 OS updates, 5 years security updates), good battery, 1080p amoled 90Hz 800 nits.

Tor bridge/relay and i2p node

Snowflake and i2pd could work but not in the best conditions.

A tor guard/middle relay or bridge/snowflake and i2pd node.

If you look on this plex support page, they say you need around 8000 passmark points, if I were you, I will look a cpu which a bare minimum of 10000 passmark points to be fine.

I just come back to pirate bay again, for tv shows and movies is fine

Using i2p for torrenting

Not for China. For example nytimes.

Debian 12 with xfce

On ed2k/kad network you have some results

In my servers I use debian 12, but I think a good balance (stability & up to date packages) would be linux mint in my opinion.

EEE

I recommend debian 12 works like charm

Well for calendar I use too the default app, but my usage it is pretty basic.

For me is good enough to not use the google ones.
