New Computer

Hey this is my 1st time building a computer and i was wondering if anyone here could tell me if all the parts i picked out would be compatible together, and if all the things i have listed will be ALL that i need to get the computer up and running. Also if i could replace any of the parts for many something a little cheaper thats just as good.

i've taken a computer class for the last year (7th), and so far we've only learned C++
my teacher joked about hardware hacks, and i would like to know how to do this, thank you.
