This is my first purchase of a renewed computer.  I looked at a lot of systems on Amazon, and settled on this Dell Optiplex 9020.  It arrived in great shape, almost can't tell it's a refurbished unit.  Only a couple of minor surface scratches that were fixed with a Sharpie.  Clean on the outside and inside.It is configured exactly as it was described.  Fired right up.  Nice to see lack of bloatware.  I gave it two stars for gaming, as it's not configured for such.  I picked up a Startech DP to DVI adapter, works fine.  I am looking at some upgrades in the future, including a larger wattage p.s., along with an SSD and a discrete video card.EDIT 10/14/2020:  I've made the following upgrades:  bumped RAM to 32GB, added RX570 4GB video card, Corsair 650w power supply.  I purchased a 2.5" Crucial 1TB SATAIII SSD.  I have yet to install it, as I'm still wrestling with changing BIOS over to UEFI, which will necessitate a clean install of Windows 10, or simply doing a drive to drive clone.  I agree with the poster that indicated bumping the RAM from 16 to 32GB didn't make much, if any improvement.  I did it mainly to make sure DDR3 was still available, at the right price.I also picked up a refurb Dell 24"monitor, for the ridiculous price of $60.  I remain pleased with the original Dell purchase.
