Really like these used units. Very high quality. Have four of them in service. Two in the office for business use and two in the living room next to our recliners with monitors mounted on swivel arms and wireless keyboards with included mouse pads. Just great setup for News, Movies, You tube Video's and online classes. Run Win10 only (hate win11). Actually ended up with one defect which was replaced no charge by the supplier, so I guess one problem out of four was not bad odds. First unit bought is over a year old, still works great. Don't know it these would be good gaming units, since we don't do that (we are old people). Very satisfied. Saved thousands buying used. Dell Optiplexs seem really good.
