08-03-2026The HP Pro 400 G9 Mini PC Desktop Computer offers silent operation for most tasks. But I don't use it for heavy power operations like video post processing. It is a heavy, robust build and has amazing power in a micro footprint for a desktop! There are plenty of ports both front and back. It comes with built-in speakers, but sound is very tinny. Even so, none of the other desktop computers I've ever bought have any audio speakers built in them. So tinny or not, it is a welcome option. It sets up pretty easy, as far as Windows 11 computers go. Overall, I am very happy with it. I plan to buy more of the HP Pro 400 G9 Mini PC Desktop Computers for light to moderate computing power needs in the future. If things change, I will update this review.Daniel D.
