Also wanted to add my opinion to this thread.  I too thought the wifi was integrated but I got over it - the supplied wifi dongle works just fine.  Computer chasis was perfect on arrival and it took little time to get it up and running - it just needs updates to WIN10 not a complete download.  Also, if you buy, check the drive for some latent information from the prior users.  I was able to clear out nearly 30 gb of data from the memory and now have about 205 gb  (out of 240 gb) left for my use.  Don't do a lot of downloads and no gaming so this size memory is just fine for me (I use other music sources, Prime, Google so don't need to download any music or media).  I can hear the fan but it isn't annoyingly loud - just 'present'.  Had to buy the stand separately - which I recommend doing.  Keeps computer stable, upright and cooler.Hate to review so early on as I'm always wary of first impressions but this is a great little computer at a very good price.  I have had one other tiny form computer before and this one is way faster - logging on and loading webpages is a snap compared to my last mini-computer so I'm really happy with this one.  This one cost about 150 dollars less than the first one (i3, 500gb) and that was purchased 3+ years ago.  Will update should anything bad happen between now and next Christmas.  I JUST WANTED TO ADD - I BOUGHT THIS FROM AMAZON - NOT A 3RD PARTY SELLER.  IT WAS REFURBISHED BY ANOTHER COMPANY BUT SOLD AND SHIPPED FROM AMAZON.
