The HP EliteDesk 800 G9 Mini keeps the upgrade options flowing

HP continued the accessible design with the G9 Mini. The wireless card is a removable M.2 2230 module supporting Wi-Fi 6E or Wi-Fi 7, and both RAM and storage are user-upgradeable. The CPU cooler can also be swapped if you’re chasing better thermals.

One gotcha: the power supply is internal and non-upgradeable. What ships is what you’ve got. But everything else gives you room to breathe — this is one of the more tinker-friendly mini PCs on the market.
