The RAM has always been the biggest issue, for me. I'd almost always prefer to have my larger data on an external system. In my case an NAS or several RAID enclosures. Having the data "mobility" is important. My normal workflow is to have my active work on the system in question and then move it back forth as I finish or swap projects. In recent years, I have never maxed out my storage on my Macs. To be fair, I don't work with a bunch of 4K video editing, or other huge datasets, so maybe that's where it becomes more of a problem.
