Which Mini ITX Board is Best?

I am in dire need of advice for my next build in the Bitfenix Prodigy (Gaming/LAN rig). It would be a toss-up between these three mini itx boards:

http://teksyndicate.com/news/2012/07/19/evga-release-mini-itx-z77-motherboard (of course, considering it will be out in the next month and a half)

My main concerns are with power delivery as I will be slapping my overclocked GTX570 Beast Edition (Core:870;Mem:1900;Volt:1063mV), i5-2500K including an H100 in a push-pull configuration (overclocked to 4,2Ghz), an OCZ Vertex 3 and a Seagate Barracuda 3TB hard drive all running off a Silverstone SST-ST85F-P 850W power supply.

The Asus board seems to have take care of the power delivery situation with their beefy looking power design protruding vertically from the board. However, the Asus board is horribly over-priced is my opinion. How does the Asrock board compare to the Asus one considering the current overclocks on my system? I am well aware that the EVGA board has not yet been released but is there any indication to how it will perform?

Thanks in advance for any help/tips/advice

All the best

ASUS P6Z77-I Deluxe. No doubt.

Definitely ! Fantastic board. Plus the CPU is centered which is rare and pretty nice for beefy aircoolers. I suppose you'll be running the h100 in place of the ODD ?
Would you mind putting up some pics when it's completed ? 

Wow, thanks for the responses guys! Much appreciated :)

Yes, the ODD will definitely be the first to go together with the top HDD cage. I mean, that top HDD cage is only useful if you are planning on building a storage server. But this case is waaay too purty to be unseen in some dodgy, dark and dusty corner of the house. Plus, there are additional mounts for SSDs somewhere in the case...if I am not mistaken.

I will most definitely be posting pictures of the completed build; either here or on "Show me your insides"

One more question: Would the new Corsair SP120 (Static Pressure) fans from their Air Series work well with the H100? Additionally one AF (Air Flow) fan for the case intake and one for the exhaust?

Cheers

ps: Black or white? Hmmmmm

The SP120 would definitely work with the H100 [I remember seeing a video on OC3D w/ H100 + SP120]
I heard they're great little fans, but I never tried them. Love the color rim on 'em !

If you want great air flow and super uber quiet fans, I recommend BeQuiet!. Not sure they're available across the pond though.

As for black and white, I'd take the black [better airflow with the mesh in the front ;) ]

I would definitely go with the ASUS board. That thing is a beast of an ITX board.

There are SSD mounts on the right side panel.

The SP120's would work great with the H100. They perform almost as well as the corsair stock fans, and they're a lot quieter.

I would go with black. I prefer black over white, with the exception of the Corsair 600T. Not to mention the black model has mesh in the front of it.

ASUS board is better, I personally would not get it after what happened with my Rampage III Formula (Really long story).

If you want to save $50 get the ASRock.

I really doubt you need the ASUS board to overclock a 2500k to 4.2Ghz.

@Vortex88 : Are you saying the SP120 enthusiast edition fans are quieter than the corsair stock fans? Or were you talking about the quiet edition ones?

@ChaosBlades : It's not only the CPU overclock that I am worried about but also the power delivery to the single PCI-Express x16 lane with my power hungry, overclocked graphics card. Maybe it is just me being overly cautious but it is pretty obvious that one cannot fit as much circuitry and as many capacitors on a mini-itx board as on a standard atx form factor.

@eeeple : Yeah, black definitely has better airflow ;)

Once again, thanks guys for putting in so much effort. I only reigestered with TekSyndicate yesterday...but I am already really starting to like this community.

Cheers
