The only hard part about building a PC is holding the processor in your hands and realizing how fragile and tiny it is; and expensive. Then trying to clamp the little arm thing down on the motherboard and having to use so much force you're 100% convinced you put it in wrong or something then having to double and triple checking the pins then trying again and almost having a stroke when it clamps in hard and you think you broke it and are out $300-500 and theres nothing you can do about it
It's like a ritual everyone that builds a PC has to go through
or maybe not this last time around I don't remember it being difficult at all
You've probably already built a PC but I wanted to ramble on anyway
