I go for the unoriginal but oh so simple: location-type-No

So HL-SRV-01 is “homelab server no 1”

HS-DSK-02 is “House desktop no2”

NA-LPT-01 is “Not Applicable” because this is my admin laptop that I expect to move around a lot so I always treat it as high-risk.

Same vibe as:

“I won’t work overtime because I end up losing money on taxes”

That’s not how tax brackets work!

“100% made of Cessna concentrate”
