The beefy computer requirements are really just the result of needing to invent pie-in-the-sky specifications for the website, and wanting to avoid any bottlenecks when running at high load. Remember, most of the current customers are trying to actively communicate with an enormous number of contacts.

The truth is that the product does not actually need much RAM, and storage is a direct function of the number of conversations and messages you're handling with the product. The main bottleneck is really just I/O for the databases. For the use cases of everyone here, it absolutely could run on an RPi. Easily.
