like scragnoff said,
1. loose the sound card. if you want a good one they cost more and the mobo sound is fine if not.
2. personally, id change the case, it's not worth pouring money into what is literally a box. just get a decent 40 or 60 dollar one.
3.power supply is excessive, get a better, lower wattage one
4. HDD: Western Digital or Seagate are preferred, but others work too.
also, i'd personally go for a better mobo if you plan on getting an 8 core cpu and a 680. you don't want to go cheap on what connects all of your components.
What are you going to use this rig with? Games, graphics designing, and/or audio editing, etc?
I'm asking because if you're not into professional sound editing, then you won't need the sound card. The onboard sound is more than adequate.
Your power supply is too much. Go for ~500w, and manufacturers like SeaSonic, XFX and Antec. Make sure it's also rated, e.g. 80+ Bronze.
16 GB of Ram for me is excessive, too. But, if you're into graphics designing or whatnot, you will be able to make use of it. Besides, Ram is very cheap nowadays.
You do need a Hard Disk Drive. Go for 1 TB, preferably by Seagate. I would also suggest getting an SSD as your boot/application drive, preferably 120 GB or higher.
Thanks for the advice ive gotten rid of the sound card and im looking for a new power supply, ill need the 16gb of ram because i do graphics design at school and i forgot to mention i already have a 1tb HDD but ill have a look for a good cheap SSD.
