Building my first computer

Alright, I’ve set myself to building my next computer myself. I’ve spent many hours searching for parts and I want the input of all my fellow kirupans.

Most of the parts I picked out from and I have heard more then a few bad things about them so I’m very nervous about ordering from there. What do you guys think of them?

Also wanted to check and make sure I’m not missing anything and all my parts are compatible. I have to cases shown because I haven’t descided which one I like better yet. I also am not sure what power supply I need.
