Finally replacing the 2017 home iMac (the one that can only run Ventura) too. Family was at the Apple Store this morning checking out M4 iMac colors; only 4 of the 6 were on display and somebody wanted to see the yellow iMac in person, so it looks like it's probably be Silver or Purple then.

In preparation I ordered a USB4 enclosure and a 4Tb SSD stick at Black Friday sale prices, and we'll use that drive as the boot drive.
