Building new PC with parts from old

[gramzon]

I'm in a bit of a predicament, I currently own a gaming PC, I think my motherboard is dying so I want to replace the motherboard/CPU and CPU cooler. While doing this I want a better case to accommodate a dual radiator closed loop CPU cooler as well. My current PC specs are:

 

 

My PC specs are as follows:

 

Intel Core i7 2600K Unlocked

2 x EVGA 780ti in SLI

Asus ROG Maximus IV Extreme-Z

Corsair H80 CPU Cooler

8GB (2x4GB) Corsair Vengeance Blue

1000W PSU, Coolermaster Silent Pro

256GB Samsung 840 Pro

Silverstone SST-FT02S USB 3.0 Fortress Full Tower Aluminium Chassis

 

Now, I was hoping someone can recommend a good case for me that can accommodate all my parts with a dual radiator and excellent air flow cable management etc.

 

Also planning on buying a CPU/motherboard/RAM pre-overclocked bundle from scan.co.uk as I'm totally useless with overclocking and would prefer it done by a professional and it be stable so that I can enjoy using my PC, any recommondations on which one would be good? I was thinking of the 4770k overclocked to 4.6ghz with the corsair H100i. http://www.scan.co.uk/3xs-overclocked-bundles

Which motherboard would accomodate the 2x 780ti plus I want to add my big foot network card plus a new audio card as well?
