Old desktop hardware works pretty well as a server for homelab/personal use. My server is mainly cast off parts from my desktop, and initially it was using a 4670k + 16GB RAM. Running vaultwarden (nee bitwarden_rs), jellyfin, gotify, graylog, Foundry VTT, unbound, a local Arch package repo, calibre-web.
Performance was pretty fine, it turns out even services like jellyfin and foundry don't have much in the way of idle usage and a personal server doesn't have much in the way of multiple users. It's since been upgraded to a 3900x, mostly to justify 3900x->5900x upgrade in my gaming machine, but also because there were two tasks it got cpu bound:
1. Running multiple h265 hevc to h264 transcodes for jellyfin - I don't have a GPU with supported video acceleration support, since both the r9 290x and igpu on the i5 were too old for both h265 decoding or h264 encoding.
2. Writing to my storage array was actually CPU limited (it's got lvmraid raid 6 on LUKS devices, LUKS on LVM would likely have worked better than LVM on LUKS here).
