In a word, its fast.  It helps that the vendor provided a 500GB NVME SSD and 16GB of ram, but that alone doesn't explain the speed which I suspect is the result of careful engineering on the part of HP.  I generally like HP business computers as they have toolless cases. This one is no exception.  It opens with latch in the back. There is a bracket to hold a 3.5" disk that lifts up on a hinge and can be removed. HP provides a power connector and SATA connector that are not used as the refurbisher installed the SSD on the motherboard which is very convenient.  The interior of the PC was professionally cleaned and appeared new.  The unit is very quiet -- I couldn't detect the fan sound though its not fanless.  There are plenty of USB ports and two displayport connectors on the back.  The refurbisher provided a displayport to HDMI adapter in the box that came in handy as there was no VGA port on this model.I also appreciated the Windows 10 Pro that came installed on the PC as it allows activation with a local administrator account.In all, this PC is great value and certainly very fast.
