disappointed to see them still selling these with 8gb RAM. More than a dozen chrome tabs and a few discord servers has been enough to crash/significantly slow down my m1 mac mini edit: the ad says up to 24/32GB of ram, but seems like 8gb/16gb models are the only ones available for pre-order at the moment.
The thing to be careful of is if your custom config breaks then the turnaround to fix it can be a couple of months. Ergo only buy stock configs. That makes the market somewhat less friendly.
