The full description, from the linked ABS document is:
"Processing units (excl. processing units for personal computers & those of 8471.41 & 8471.49) whether or not containing in the same housing one or two of the following types of unit: storage units, input and output units"
8471.41 and 8471.49 according to [1] have ANZSPCs of 45200.10.10, 45200.10.90, 45200.20.10 and 45200.20.90, which according to [2], represent:
- Mainframe, mini- and super- computers
- Other multiple-user computer hardware
- Desktop computers (PCs)
- Other personal computers
TL;DR: A quick Google could have shown anyone who cared to look that the granted restrictions explicitly exclude "CPU and/or server sales". Great journalism.
