I7-3770K 3.5Ghz Microprocessor - Perfectly fine, I would suggest looking at Haswell if it is an option though, the stock performance is better and if you are getting the Corsair H80i (which I have in my personal rig and love it), you can overclock it further (performance-wise) than the 3770k.
16GB(2x8GB) 1866 G.Skill Low Profile Ares RAM - Any specific reason you are getting Low Profile? It isn't a problem, but G.Skills Ripjaws X (of which I have 16 GB in my personal system) has some great heat spreaders that allow for better overclocking if you are interested in OCing your RAM. Corsair RAM is also wonderful if you decide you don't want Low Profile and don't want G.Skill.
Samsung 840 Pro 256GB SSD - I have a Samsung 840 250 GB and it works wonderfully. Have a blast with the pro version, it only gets better.
Seagate Barracuda 2TB HDD - Have one, love it.
Seasonic SS-760XP2 Power Supply - Seasonic and Corsair are my two preferred brands for PSUs.
Asus DRW-24B3ST DVD Burner - Aslong as this is your cheapest option, I agree with it.
Thermaltake Overseeer RX-I Case - Haven't had a chance to build with this case, I personally don't like the style but that's all up to you!
Gigabyte GV-N770OC-2GD Graphics Card - Great card
or
Sapphire 100351SR 7970 OC w/Boost - Also a great card. I prefer the 7970 as I have a 7950 in my build and LOVE it. I have 3 displays set up with a single card, and could have a 4th if I wanted. Just a fair warning, the 7970 requires that you use the onboard mini-DP for driving any monitors beyond 2. If you want to have 4 connected, 2 of those MUST be connected through the DP on the card. If your monitor doesn't support miniDP/DP then you must buy an ACTIVE adapter (they run around $30 each unless you require the dual-link DVI to drive displays larger than 1920x1200 which are $100 each). The 770 you mentioned does not require this, but I prefer AMD's drivers for multi-display.
Cooler Master Hyper 212 EVO - Awesome budget cooler.
or
Corsair H80i Micro Cooler - Great closed-loop water cooler. I have one, and I love it. Tip though, the provided fans are a little loud and are only mediocre performers. I personally suggest the Scythe Gentle Typhoon 1800 RPM fans. I have 2 in push-pull (no huge benefit, it's for aesthetics). They are expensive at $20 each, but they are wonderfully quiet and outperform the louder stock fans that come with the H80i.
Hope this helps!
