If you ever plan to use any of these older PCs: Disable Spectre and Meltdown mitigations! As a bonus you should also remove CPU microcodes from the BIOS/UEFI and make sure that no microcode is loaded via software.
The performance gain is huge if done correctly. There is no need for these mitigations on homelabs.
