Quality alternatives to Yellow? Case (Pi and SSD) + Heatsink/Fan + ZigBee

Hi. Looking for possible alternatives to the Yellow as it won’t be available until end of March.

I don’t have any Pi components currently. This is for a new Home Assistant installation.

The Argon ONE M.2 looks good, to which I could add a Home Assistant SkyConnect.

Any others I should consider?

Anyone know if the Yellow may offered with a 4GB Pi in the near future?
