You've also chosen the unlocked version of the CPU which might suggest you plan to OC it. If that's the case, you might want to bump up the PS and make sure it can supply the needed amperage.
So I have decided for the first time to build my own PC, my last two PCs were store bought and both honestly weren't as good as how much I paid for them. Some friends have told me to build my own so I did my research and basically copy/pasted a "sample build" from another site. My biggest fear is dropping $1100 on a PC and then when putting it together finding out the Motherboard is incompatible with something or there is not fan/an insufficient fan for the heat coming out etc. So what I'm asking of you very smart people here at CNET is if you could tell me how to confirm that these pieces will work with each other or just flat out tell me they will/won'. Thanks in advance for all of your wisdom!

Also let me know what you think of the build, if there's anything I'm missing/something that could be improved upon. I'm basically at max budget so I can't really "upgrade" anything but if there are any serious flaws I would like to know.
