I've recently been looking into working on a new project including a raspberry pi. I want to make the system slim, with a keyboard and mouse, battery powered, wifi capable and i was hoping to have the whole system about 2 inches tall. Can anyone recommend me a wireless keyboard and mouse combo that are both hooked up to a single tiny usb and the keyboard must be about .25in thick. I want to try and build this system into a case with the keyboard on top and all the hardware built in underneath the keyboard.
