this one is my first, and i'll be having some friends help me assemble it so i dont break anything

but, i've been looking on newegg for parts, and i've come up with a list. can you guys tell me if its ok, or if some parts are incompatible? also, do i have everything i'll need, and can i get cheaper parts that are still top of the line, or is this the cheapest i can get?
Thanks! i appreciate any help
