BTW -- not *everything* is nearly as complex as Luke would have you believe.

If I ask about how to build a libre software mainboard into the cabinet of a common notebook, lkcl gets rather hectic on rebuffing such option. Some of his arguments I accept. Others I do not. One lkcl argument is, I should not spend thousands of usd on making an attempt with an uncertain outcome. I agree on that. For now I have spent 50usd on getting an asus 7inch eeepc. I like the size of it. It has a full keyboard. It is bulky. Therefore more likely to have space for building in another mainboard. Lkcl says, should I succeed in building one, only I would benefit. I disagree. I would tell others how to make a similar computer, should they want to. Then lkcl has this argument about reverse engineering a lot of computer devices. I do not understand it. Apart from the display all devices should be usb. Sound, touchpad, keyboard, ethernet, wifi, storage. Display should be hdmi. Rather I believe getting a battery and powersupply solution would be difficult. I would also like to make a libre software computer looking like the pocketchip. I have bought this generic 6usd keyboard. https://images-na.ssl-images-amazon.com/images/I/51q2r5Jvu2L.jpg I do not like the feel of the keys. Apart from that it is adequate sized. The keyboard does not work via usb wire. It would require the keyboard to get modified.

Keyboards are invariably a passive switch matrix (look it up if you don't know

About the asus eeepc's keyboard. I have. I am not clever enough. Lowpriced on ebay I found an ATMEGA328P-PU Microcontrolle​r. A GPIO kit Extension Board Adapter Breadboard. A flat cable Ribbon connector socket 30pin 1.0mm Pitch. Apparently using a raspberry pi, you should be able to program the microcontroller. How to make the keyboard's matrix, I do not know.

Touchpads are almost always either USB or PS/2

What I have been told.

It's the screen and battery interfaces that are going to get you

This rk3399 mainboard https://www.cnx-software.com/2016/12/05/firefly-rk3399-rockchip-rk3399-devel... has a hdmi port. What should be the difficulty in connecting the mainboard to a hdmi display?
