I had to replace an Ibuypower PC purchased in 2014 from Newegg. I did some research and decided to focus on the Intel i5 processor or the AMD equivalent.  I knew that I wanted at least 8gb of DDR memory.  I was checking between Newegg and Amazon.  I saw some good reviews on Amazon for this refurbished PC.  I was impressed with the 90 day warranty for this refurbished machine with a direct number to Amazon. When I unboxed this PC, I was impressed with the packaging. Everything was included to set this PC up. SunsetMicro provides a very good  troubleshooting guide for this setup.  Occasionally in shipping, some PC's have components that are accidentally jarred out of alignment.  The troubleshooting guide provides pictures in color to determine what the problem might be. This PC has 16 GGB of memory, 2 TB HD, a HDMI video out, and best of all, 6 usb slots. There is also a youtube video out there on how someone was able to significantly upgrade this PC by adding a 4 gb video card  and a SSD hard drive . This is a great deal for $210.00.
