And the v3.0 touchscreen is the latest you can get. The E3 display fits your housing and is definitely the part you should get. The 7" tft70 comes with a 168mhz running processor, the same as what drives the SKR PRO, GTR1.0, and BTT002 but you would have to draw up and print out a mount for that. Or you could just find someone else's design that will attach to your printer frame. Like this: TFT70 V3.0 Case and Adapters. by Portzal - Thingiverse . I have my own design to mount on the top of a really large printer frame but I haven't yet shared my design on thingiverse..
