Had to scrap last build, input on this new mATX build?

I readily agree.

And here's a couple more PSU options:
SeaSonic S12G-750
Antec HCG-620M

Definitely agree with other people, you are spending too much money on stuff that will not help performance.

The 4670k was an reasonable choice over the 4770k as ya saved $100 and gave up just 0.1 Ghz.

But with the 4690k being a 3.5 / 3.9GHz and the 4790k being a 4.0 / 4.4 GHz CPU it' a different ballgame. That's a 14% difference at base speed rather than 3% with the old CPUs.

If ya look at it from the usual standpoint, not very attractive ...14% performance for a 42% increase in CPU cost. But this just seems silly. Is it your CPU that will go faster or your whole box that goes faster ? So on a $1200 build, is it worth it to go 14% faster for a 8.5%, very different way to look at things. Still if it came down to

4690K ($240) = MSI 780 Ti ($600) = $840
4790K ($340) = MSI 780 ($450) = $790

I immediately wanna say id take the $790 option if I had to ..... but methinks I'd more likely wait a bit and get the $940 option ....

I'd lose the H80 and get a Phanteks PH-TC14-PE air cooler quieter and same temps and saves $30. It will also give ya 7 - 10C better temps than a Hyper 212.

The 780 EVGA Classified is the top card but most reviews put the the SC is the "bottom of the barrel" . Since that review MSI retooled and their card is much faster and much cooler then the Asus which was No. 1 in that review.

Id take the MSI 780 and 4690k if it was a gaming box for +$20 ...so we still $10 ahead over your build with the 770

Id get a PSU capable of doing SLI in future. The EVGA 850 is just $15 more ...but the XFX is $15 cheaper......so if we go that way, we $25 less than from your build

$95 http://www.newegg.com/Product/Product.aspx?Item=N82E16817207011
$120 http://www.newegg.com/Product/Product.aspx?Item=N82E16817151108
$120 http://www.newegg.com/Product/Product.aspx?Item=N82E16817438018

I was gonna change the MoBo and case but ya seems set on a micro ITX build.

If ya willing to go bigger case, the Corsair is again at a ridiculous price of $88 after 10% off w/ promo code GACASETEN, ends 7/23 and $20 MIR ..... that's another $72 saves + $25 you now saved $97
http://www.newegg.com/Product/Product.aspx?Item=N82E16811139010

Id then substitute this combo and upgrade you to the Z97 GD65 w/ the same GSkill memory for just $3 extra
http://www.newegg.com/Product/ComboDealDetails.aspx?ItemList=Combo.1734248

net savings $94 .....

But the $48 worth of extra fans now become unnecessary in the 500R so our total savings is $142 which leaves ya just $8 short of a MSI 780 Ti

here's what i say about that .....

i7 to i5 is no loss. 7770 to 780 is a gain.

Air coolers are generally quieter than water coolers.

All custom coler graphics cards have ample cooling. Some better than others. For the 780 I like Asus. Jack says MSI is now better. For a R9 290, I like Gigabyte (good price) but others like Sapphire

Silverstone power supplies are not as good quality as Seasonic, XFX, EVGA Supernova or Antec HCG per http://www.tomshardware.com/answers/id-1804779/power-supply-unit-tier-list.html That's why we are recommending them.

You are spending way too much on the Case

Changed the case to a cheaper one and got a fully modular PSU

I agree - too much on the case. Try a BitFenix Colossus instead

Depends.....

The 4770k over the 4670k gives ya 3 % (stock) - 6 % (OC'd) performance improvement for a 6.7% increase in cost on your $1500 box.

OTOH, the 4790k (4.0 Ghz) gives you a 14% performance improvement at stock (can't tell ya at OC as little experience as yet) over the 4690k (3.5 GHz) for the same 6.7% cost increase.

The blower style card is costing you an extra $50 for less speed and way more noise. I would find the AIO cooler and the blower style GFX card to be way to loud for me to sit at the puter under load very long. That $50 savings would put you half way to a 780 Ti. A more roomy case that would let the cooler and GFX card breathe a little would supply the other $50. I find those micro cases, while convenient of ya move them a lot, significantly limit OC's on both GFX and CPU.

Changing the fans for quieter ones on the AIO generally puts you at a thermal performance level less than a $25 Hyper 212.

The only time I buy full modular is when I am going to re-sleeve all the cables. Hybrid modular, where the absolutely necessary cables are hard wired (thereby increasing efficiency, eliminating potential failure points, reducing cost) and only cables that you might not use, is a superior solution. You can't put together a build w/o a 24 pin cable, PCI-E cable, SATA cable and EPS cable, so what is the advantage them having it modular ?
