 Running a node has no specialized hardware requirements. People were successful at running a node on Raspberry Pis, for instance.
 Minimum requirements are moving targets due to the nature of the project and some factors should be considered:
 
-- compiling node sources locally requires processing and storage resources
-- replicating the chainstate requires significant memory allocation (1,3+ GB)
-- chainstate size grows over time, increasing the memory requirements
+- compiling node sources locally requires computing and storage resources
+- as the chain grows, the on-disk state will grow over time
