Bought it for running a test node for a digital coin blockchain network so I can free my PC.  Good budget setup with all the things I need.  My unit does have build-in WiFi but it is very weak, pretty much useless but I don't care.  It also have a WiFi adaptor and I did not use it.  Meant to leave it plugged-in at my router all the time.No complains.  5 stars.
