HP mini there, with ZRAM it's really fast. I use Flubox+UXTerm+a bunch of CLI/TUI tools among mpv, nsxiv and mupdf. The OS I use it's hyperbola GNU/Linux, A bit outdated but most modern stuff it's compiled from source. For gaming I have mednafen, frotz, pcsxr, Flare RPG (git), GearHead 1 and 2 and a few more. Oh, and Scummvm with games from Blade Runner to Ultima I-IV, Technobabylon, Virtuaverse, The Longest Journey, Sierra and Lucas Arts games and about... ¿2000 games more?

For the web I use DIllo and a custom build of Otter Browser against the older QT5 Webkit engine.

For web media I use streamlink and yt-dlp.
