Accomplish one of my dreams of building a gaming pc

i was a gamer since i was young. started with ps1 and still going. tried to build pc on my own so i bought a mother board and a case, and thats it. had no more money to get the rest of the parts. so i had to sell the motherboard after sitting on my shelf for few months at half of price i paid for. not gonna lie, i felt sad and dumb at the same time. now i saw this website on one of the videos and i said f*** it, what i've got to lose.

id really appreciate the help with any amount, and hope someone would do the same for you someday.
