The following servers are old (> ~4.5 years old, sometimes > 5 years old!) and are either spare, or just unused, so they should just be decommissioned and unracked. Please **double check** whether they are not online/unused and do follow the steps of the checklist (wipes etc.) before decom'ing.

(note that lawrencium is online, but with role spare::system)
There are also a few more that are ~4 years old, and we could keep them as spares for a while longer, so let's **NOT** decom these just yet:
