I like the POP 7" Touchscreen Kiosk – Case by metaphorraccoon a lot. It looks great, has several mounting options, and several other features. There is a maintenance port to access USB & LAN connectors with removable cover, which makes it suitable for an octoprint panel.

With all the weight of the cables on one side, the original stand (POP – Modular Mounting System Foot) is too weak. Therefore I designed these simple brackets which mount to the back and bottom holes. It also holds the USB SSD (Pioneer XS03) I use instead of an SDCard.
