Love this PC
Solid mini computer perfect for most office tasks and light video editing/graphics work. Performance is good and I love the form factor, I install it under my desk for more desktop space. No fans so I have installed a $12 fan under my desk to cool it. This is my second Mini and I'm not sure I'll ever buy another desktop form factor again.

Performance of HP Pro Mini 400 G9
I'm pretty disappointed in the HP Pro Mini 400 G's performance.
I don't think that I would consider HP hardware in the near future.
