Like many other things nowadays, computers have become disposable. For $180 you get a little more than what you paid for. This is a solid no frills machine that is fast, quiet and works well. I have not had any problems and Windows 10 is great. I am a web developer and use this with visual studio and photoshop. I also use it to stream my music collection via Plex. I have 3 external drives in the USB ports that are working fine.  If you are purchasing one of these refurbished systems be sure to get at least 8GB of ram. I am expecting to get 2-3 years out of this machine at least. If that happens I will be more than satisfied. I do not think I will ever buy a brand new computer again.
