This is one of the most asked question on the Optiplex forum. The Optiplex model -especially an all in one-is not a computer for video editing or gaming. That 7 yr old model is intended for business use. It has an extremely small 200 w power supply and upgrading is impossible. The all in one is more like a laptop than a desktop with hardware integrated on the board. See the board illustrated in the setup manual https://downloads.dell.com/manuals/all-products/esuprt_desktop/esuprt_optiplex_desktop/optiplex-9020-aio_setup%20guide_en-us.pdf
