BUILDING FASTEST COMPUTER! (help needed)

[glenntamis]

what's up everyone i'm new to computer building and i want to purchase the right parts for the fastest computer for the cheapest price possible. i want to get a computer that i wont have to wait for booting, transferring files, surfing the web, etc... i'm starting in my head to pay up to 500$ U.S. but if things speed up much or even a little more with the shelling out of more cash i'd for sure consider it because time is money.

i know this is a very general question but i'm willing to read up a lot on the different aspects of computers if you give me the links.

so where do we start... is there any downside to building a comp yourself besides having to put in the work? from what i know the parts purchased separately are much cheaper than buying them together, let alone put together in a laptop and that's why my plan is to put the computer together myself.

anyways, i appreciate anything you can do to help. thanks a lot in advance.
