Oh God, First PC build

Hello, first off i'd like to let everyone know i'm a complete noob to the PC building scene.
So i'm building my first PC and I think I got the gist of it. Here's what im getting

1. 2GB XFX Radeon R7 370
   
2. ACE 600W PSU
   
3. AMD 6300 FX CPU
   
4. Gigabyte 78LMT-USB3
   
5. 8GB DDR3
   
6. CIT CASE
   
7. Crappy Optical Drive
   
8. Obvious other peripherals
   

So is there anything else I may of missed or need to specifically do?
