Ok. Upon unboxing,  I was initially disappointed in the monitor, because it looked so old and worn. And the screen was quite small. I was expecting something more like the sleek 17' monitor in the description photo.  It didn't have to be new.  But this one looked to be about 20 years old. LoL!Still I'm a student on a Budget--and the semester had started-- so I HAD to make it work.  I swapped out the monitor for a 19' flat screen TV I had lying about,  and I was soon in business.Initial disappointment aside, Ihave to say I am very impressed by the CPU.  It's compact, but very powerful--and  it boots up in just a few seconds. After plugging the WIFI adapter in, the computer connected to the internet with no trouble at all.(Note: Wi-Fi is NOT built in to this unit.  Make sure you locate the plastic adapter before throwing out packaging).After that,  I was away!  I've been using the computer for about a month now and it's been great with zero problems.I"m giving the system 4 stars because of the monitor.  If I had to do it over,  I would have bought the CPU and purchased peripherals separately.  But the computer itself is excellent and  performing well above my expectations.  I am very happy with it!
