Would've Given 5 Stars, Except for the fact the at initial login a Trojan popped up, Embedded in 3rd Party Driver Update Software, which came preinstalled. However, Windows Defender immediately caught it and quarantined it. Otherwise, the item looked Brand Spanking New Inside and Out. Opened it up upon delivery and looked like it came directly from the manufacturers clean-room. (See Pics) Two Fans...Both Spotless. Everything, spotless. Booted up within 4 Seconds with the zippy SSD. ZERO issues or concerns after several days, but time will tell. We had these same towers in the USAF and they're absolutely reliable work horses. As with any third hand device I do recommend Multipass/Overwrite Drive Wiping and Reimaging the OS. You never know what was on it before and you don't want the FBI Forensics team kicking your door down. I have it hooked up to my 65" 4K TV via a Display port to HDMI Cable and the picture is Amazing. (Cables are like $6 on Amazon) Will update as time passes. Very impressed thus far.
