    Rated 4 out of 5 by Originaldiscokid from 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.

    Rated 2 out of 5 by y2krok00 from 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.
