I got a junk Precision workstation last year as a "polite" home server (it's quiet and doesn't look like industrial equipment, but still has some server-like qualities, particularly the use of ECC RAM). I liked it so much that it ended up becoming my main desktop.
My main desktop is temporarily a Dell server from around 2012 or so. Two were thrown out, each with two 2 GiB sticks of RAM, so I poached the other machine's RAM for a grand total of 8 GiB. I also threw in a small SSD for the / partition (/home is on the old HDD). The thing is dirt slow but I never notice, even YouTube video playback works fine. Even on hardware well over a decade old, Debian runs fine.
