but are the parts compatible and will the v8 if i do get it fit in the z77 saber tooth
Rest of your parts seems okay, the DF case is a little slim, so I'm not sure if the cooler will fit height wise. Why not an Antec 302 ? That will fit the tallest of coolers and has a cooling performance far, far better than the DF (which is actually poor in cooling, combined with the V8, and if you OC, may not be great for your CPU, since you are spending the money on aftermarket coolers).
I'd also recommend, instead of the LG burner, a Lite-ON (iHas) series or ASUS equivalent.
