Making A Dream Gaming PC That I Have Always Truly Wanted

I have been playing video games since the age of 2 maybe 3 ( Im not sure which its been so long!) But my grandmother got me a PS2 and I have been playing video games ever since, skip forward a little bit and i finally learned about the world of PC GAMING! And oh my god it was some of the best times ive ever had, and that was on a really poopy laptop that I had to help me with my schoolwork, all i could really play was garry's mod and minecraft and terraria and stuff like that. But I love it anyways lmfao, when i was 12 my parents chipped in with my grandmother again (I am a very loved child but we aren't the richest so we do what we can for each other. I love my family for every gift they get me, I know its hard on them) to get me a desktop computer I have been using every since, it can play most of the games i want like league of legends and even Metal Gear Solid 5 on the lowest settings but its worth it! But now that im 18 I am working a job and trying really hard to save money to finally get that dream computer that will allow me to try and start streaming on my off time, to play the really cool new games when im able to get them. I don't really expect anyone to donate to me for this lmfao, but I would love it if you did, I will post a pic of my current computer as soon as I figure out how
