So just to make it clear, you do not want to use any of the 7020 parts except maybe the drives? What you seem to be looking for is information on a custom build using non-Dell parts correct? There is a ton of information on YouTube regarding a custom build for cheap such as this collection of videos.
I wanted to ask if anyone knows what kind of motherboard I can buy that also supports the normal cpus maybe an AMD Ryzen 9 but I don't want to spend too much on it and maybe someone knows a good case that would fit the mainboard with a lot of space for the newer graphics cards, thanks in advance.
