After upgrading from Marlin to Klipper, I add a 7" LCD touch screen on my rig. I made a custom housing for it.

Raspberry Pi 7 Inch Touch Screen IPS 1024x600 HD LCD HDMI compatible Display + Holder for RPI 4B 3B+ 3B PC Secondary Screen|Demo Board Accessories| - AliExpress

This LCD is perfect fit for my raspberry without any cables… the store already include the “fixtures” to connect the output for screen and touch.
