The only downside I will tell you right from the start is the HDD is loud. Sounds like me if I haven't eaten and my stomach is growling lol. other than that this is one solid bang for the buck machine! It came in  wrapped and boxed perfectly. When I opened the plastic it looked like a brand new machine. I mean it is CLEAN. So I opened it and it was even cleaner inside. If this machine came out of an office used I couldn't tell. It looks brand new. I added a Corsair 500W Bronze 80 PS (fit right in no adapter needed) And dropped a 1050Ti into it and it fit no problem (This is the Mid Tower model). It fired right up . Windows 10 Pro came installed. It updated and was running in minutes.  Best of all I paid 156.00 for this thing! If you are on a budget or want a GOOD gaming system here you go. Free shipping makes this dirt cheap. And did I meaning Keyboard and mouse come with it? yep. I play games and so far here is what plays flawlessly on it:DayZArmA 3State Of Decay 2Fallout 4Fallout 3 GOTYFishing Sim Worldand many many more.Love this system and would recommend it to everyone!
