Overall I think this was a great buy for the price 2 years ago when i bought it and i do not regret it. (dying gave me a chance to buy another referb with faster/newer hardware) I bought this to build a cheap gaming rig (IT DID THE JOB VERY WELL UNTILL I SAVED FOR A REAL GAMING RIG)  I pushed it to the limit with the stock power supply by installing a GTX 1650  a SSD and more ram.  The computer ran /Gammed almost flawlessly  up until yesterday when it started suddenly shutting down after running for 2 to 3 minutes after the latest win 10 update.  when testing the rig with the bios hardware check utility the computer did the same shutdown right after the hardware and memory tests were completed saying everything was healthy  Kind of funny it would get a clean bill of health and shutdown for no reason GOTTA LOVE DELL FOR USLESS UTILITIES lol.  I replaced the Power supply with a bigger one and the computer still did the shutdown sequence (problem is not power supply).  when turning back on the things i had open on my screen were still there.  power settings are set to to never hibernate sleep or shut off and to only shut off the monitor after 1 hoursjust bought another referb job from amazon and will troubleshoot this one laterI would say that this was a great buy for me and I didn't expect it to live through the hell I threw at it for so long.  the case is not much bigger then a gaming laptop and FIT IN MY BACKPACK It was easy to take with me on the go.  I don't think it is completely dead and i think that reseating the processer and ram and replacing  the cooling paste may fix the issue but if not it can be another in my collection of retired PCs that will become a naked barebone husk when other PC's in the group inherit all the  ram, drives and peripherals that are still usable!
