I currently have three around the apartment attached to the network:

One running Seafile (https://www.seafile.com/en/home/) with an old laptop hard-drive connected via USB enclosure. It acts as my own Dropbox. I mainly store notes and photos on it and sync them to a few other devices for redundancy. It also has a Samba share with all of my music and has an open vpn server so I can connect to it from anywhere.

One with a HiFiBerrry Digi+ hat (https://www.hifiberry.com/products/digiplus/) connected to my sound system via toslink running an MPD (https://www.musicpd.org/) server. I can control it with M.A.L.P. (https://play.google.com/store/apps/details?id=org.gateshipon...) on my phone. This one also has a 7" touch screen (https://www.amazon.com/Raspberry-Pi-7-Touchscreen-Display/dp...) which I use to sometimes display ncmpcpp (https://github.com/arybczak/ncmpcpp) inside edex-ui (https://github.com/GitSquared/edex-ui). This one also acts as the living room clock with an USB LED message board (https://www.amazon.com/818-Dream-Cheeky-Message-Board/dp/B00...) controlled by dcled (https://github.com/Conservatory/dcled).

Another with a GPIO breakout and breadboard with an individually addressable LED light strip attached. I got the idea from this Adafruit tutorial (https://learn.adafruit.com/light-painting-with-raspberry-pi/...). I wrote a program in Python to make it softly glow between random colors and sync to any beats-per-minute.
