Excellent reading this; My Pi4/8GB cluster uses a 1000bT PoE hub for a backplane, and / is an nfsroot from a node running a Sandisk UASP USB3 SSD. Like the author, I'm blown away by the fun to be had with Docker and Kubernetes on this cluster. Unlike the author, I'm having a great experience with it as a Mac-replacing daily driver (thanks mostly to never running chromium on the same node that runs gnome-session, to spread things out a bit). Love to read about everyone's Pi cluster adventures.
I think I could make it work, but the hindrance to my media (library of 65,000+ RAW photos from three different camera bodies and about 8 TB of 1080p video projects (and counting)) workflows was what really killed it for me.
Even basic photo import / adjustments were a pain with any of the applications I tested, and that was partly due to the Pi's slower GPU/CPU, the 64-bit ARM paucity of desktop apps, and the lack of good (read: like Adobe/Apple/pro-tier media apps) UI-based applications on Linux.
Most of the other issues (like window management and resolution problems) I ran into with the 'Pi for a Day' project I could probably resolve with a few more days' work.
