People mostly just buy a branded or already made computer but as times passes they have to get a new one! It’s better to assemble or make a computer yourself if you are looking for long term usage. It will take some of your precious time but that’ll make you appreciate the computer more because you made it and if something goes wrong you won’t have to call the manufacturer to fix it but you’ll be able to do it yourself! And you’ll also be able to upgrade it in time so you can keep up and it’s a little bit cheaper than buying an already made computer.
