Updated Review on 12-20-2020, appended extra words at end of this paragraph.  I bought this Refurbished Dell 790 computer on 6-3-2020 thru Amazon, for kitchen table web browsing, and not for gaming.  For gaming, I use a separate Intel i7-8700K 3.7GHz CPU with NVidia 2080ti Graphics card.  It works find for web browsing, checking email, reading news, watching videos from web pages, using Amazon Prime Video, etc.  But, it will not play any games other than the most simplistic video games.  I bought this computer for the small form factor size, about 4" thick.  But, with a 4" thick case and a 240 Watt power supply, you can not add in any video board that has graphics power for heavy duty games.  If you can find one, it must be a low profile card, not standard profile.  With the 240 watt supply, whenever I turn on a small fan on the same 120VAC circuit, the built in mother video circuit flashes (turns off, then back on) for a split second.  I suspect that 240 Watts is barely powering this thing!  In final, Good web browsing machine, email machine, etc.  Don't expect much.  Quality of case/product is good, as all dells are.  I used dells for many years at Boeing/McDonnell Douglas.  Roger Louie 9-4-2020Updated Information appended to this review on 12-20-2020:  This Refurbished Dell 790 has failed on this date.  Somehow I suspect the power supply since I previously heard small amounts of weird buzzing from the machine, and most if computer parts do not make noise!  Now, when I turn on the machine, the power button just flashes forever until held down for 5 seconds or so.  The flash rate is roughly once per second.  No sound or buzzing is present in this failed state.  The bootup process does not proceed.  No video signal is generated.  No bios boot is attained.  The warranty period is 3 months from purchase, so I'm out of luck.  I paid about $135 for this machine, and learned my lesson, which is, don't expect too much from a "refurbished machine"!
