I have a 4 node Raspberry Pi 4 k3s cluster that I use to run some scripts, a 4 node Raspberry Pi Zero W Cluster that I'm planning on trying barebones Hadoop on, a Pi Zero W running PiHole, and a whole bunch of Arduino and STM32 devices I use to build my keyboards. I also have samba running on one of the Raspberry Pis, with an 8 TB hard drive connected to it, for my movies and media.
