My Dell R730xd with 24 2.5" drives has no decent place to put a label with the server name. I made these little click-on labels so that I could put a label on one of the empty disk slots.
Either just print the blank label and put a sticker on it, or emboss text on it and print it with multiple colours to make extra fancy labels. See the photo for an example of how I labelled my Proxmox cluster using black labels with white text (using PrusaSlicer to change filament colours). My Proxmox design is included for reference.
