I replaced an ageing tower with this micro computer.This computer is very small, takes up almost n space - and is LIGHTNING FAST.I had the vendor double the RAM before shipping, don't know if that was really necessary but the price was right!One note - the WIFI is not via a built in antenna, but a micro USB device.  I found it's range to be VERY limited and not capable of 5GB commuications.  I swapped it out for a 5GB WIFI with an external antennae. The SSD drive is extremely fast and would be very easy to upgrade if extra space is needed.  The USB ports are all 3.0, so speed it exceptionally fast.  I also highly recommend the insurance and support package, it's very inexpensive considering the scope of support it offers.
