I have been thinking about making such a laptop as well. Some random notes: 1. IMHO, most software is crap that is only tested on i7's with 16GB of RAM. It will likely be slow on everything that has lower specs. 2. ARM =/= RISC V. ARM is a company (which has its own family of ISA's), RISC V is an open ISA. I think ARM is more mature. Anyway, you'd probably want a relatively high-end ARM processor (see point 1). 3. Perhaps a good point to start is the raspberry pi. There are plenty of tutorials on building an OS on it. This also helps you to understand the GPU. 4. One problem is that repositories for package managers focus on x86 (or x86_64) binaries. The ARM repos contain less binaries, so your favorite software may not be in there. 5. It seems that there are not many 64-bit OSes for ARM. I have tried installing Arch Linux on a chromebook and it works pretty well. Potential problem: it's hard to find the right drivers, if they even exist. 6. You probably need a degree in electrical engineering to design a laptop motherboard. I don't know about manufacturing it (or rather: getting someone to manufacture it for you), but it's probably nontrivial. 7. Bringing up Linux on a new motherboard is hard (from what I heard - I have never attempted something similar).
