Don't get me wrong, but it kinda feels you're asking for a tip, and if that's the case, innocent :D
Not only no one online would give money to a random person (even more for a goal like "I want a gamer pc"), but also you didn't even linked your patreon or ko-fi lol. Money is considerably hard to get, so unless you are a really popular person, a charity member, or something like that, if you really want a gamer pc, your best bet is to work. Like, it doesn't need to be a 9 to 5 job, or a millionaire thing, even yt videos can help, but if you want to buy your stuff, you should have your money...
