I would refer you to my previous comment but - for once! - I don't want to be an asshole. (Plus, dang would probably ban me.) This is possible in the same way as it's possible to build a nuclear weapon in a garage. There is no theoretical barrier, but out of 7-8 billion people, I'm betting the number of those who actually did it is a close approximation of zero. Where, exactly, are you going to buy a regular personal computer that comes with free - LIBRE - software in BIOS, microcode, TPM, video card, network card, and finally OS? Asking for a friend.
