What'd you think of my new build?

What's this being used for? If it's gaming, here are a couple notes:

1) Games don't (and won't) use hyperthreading well. An i5-4670k will perform exactly the same as that i7 for gaming.

2) There are cheaper air coolers that are far more reliable that cool better than the H100i... if you have the space.

3) You don't need thermal compound; the cooler will come with it. If you do get thermal compound, you want the actual good stuff, which is twice as expensive - that stuff is almost exactly the same as what gets shipped with, say, a Hyper 212 EVO.

4) You're spending too much on the motherboard. A $150-$180 motherboard will overclock just the same and perform just as well; you don't need the extra slots and features of that thing.

5) Good pick on the ram, but if you want, you can get the same or better performance for gaming from a lower clock speed, lower latency kit. After about 1600MHz, games don't care about the clock speed of the ram; they care about the latency, however.

6) I'd much rather have a 128GB SSD and a 1TB hard drive for the same money. Remember that most games and data gets absolutely no benefit from being on an SSD.

7) Great pick on the graphics card - it's got a good warranty, a good brand name behind it, and the classy nvidia cooler.

8) The case is fine, but I don't know what advantage it has over $120 cases.

9) Instead of that power supply, get a SeaSonic X series - they're better quality for the same price. Also, paying for "platinum" is like burning your wallet - there's no point. (Especially since the X650 gold performs better than most platinum rated power supplies anyways.)

10) Do... you really need a blu-ray burner? Or do you just have money burning a hole in your pocket? I'm just saying; consider it. Unless you're going to be using it a fair bit, it's wasted money.
