At least two of these are now on completely unsupported OSes that are no longer receiving security updates (and lots of latest versions of apps won't work). Especially given the uptick in major CVEs of late I'm very nervous about reconnecting any of these machines to the internet :/

My first gen 5k iMac (2014) is our kitchen machine these days. Still a joy to use. The final gen (2020) model is still my main machine.

I almost wish one of them would konk out so I can get an M series, but then I wouldn’t be on a 5k iMac anymore, which would suck. Love these machines.
