I was aiming for a budget of around $1000. Any suggestions on where I can shave off a couple bucks. Preferably, I'd like to keep the NZXT case and I might be able to snag Windows for free or cheaper in the future. I'm using this mostly for gaming and a little bit of CAD/Rendering.
A watercooling solution of that size won't give you better cooling or less noise, so I'd rather go with a decent Air Cooler. For the 4690K, I would suggest a mobo with better power delivery as well.
