if I were you I would spend alot more on the pc itself rather than its peripherals!
I'm using an old keyboard my mom used to have, and a 10 euro logitech mouse (that is fuken strong )
why are you buying thermalpaste when you aren't buying a cpu cooler? the paste comes pre-applied on the fx stock coolers.
also you went with a micro atx mobo in an atx case, this should work but seems a weird choise imo...
I would also never go with any headset from razor! all they do is bass bass bass, get an audiophile headset maybe as you already have a mic
I updated your partpicker list a little..
the mobo that it has in it should support the fx 6300 but pcpartpciker says it won't even though I have a similar mobo with an fx 4100
put in dual channel memory which is faster !
i removed the keyboard and headset didn't add a new keyboard you can do that
and added the shure srh 440 as headset (it is epic)
ok my response is late but that's because i put alot of time into it
wish you luck!
