I'm configuring a computer at this website (where you choose different parts and they build it for you, and you can choose a package and then start configuring it and change the pieces up a bit like I'm doing now).

Here is my computer specs:
GPU: gainward geforce gtx 780 3gb physx cuda
DDR3 memory: Kingston DDR3 HyperX 1600MHz 8GB
CPU: Intel Core i5-4670K
Motherboard: MSI B85M-E45, Socket-1150
Hard drive: Seagate Barracuda® 1TB S


The standard computer case that comes for free with the package is the CM Storm Scout II Advanced Gaming in black. But here are some alternatives that I can choose from and their prices (I listed the prices of what they cost if you were to buy one just by itself (without any package, etc) and not what they would cost when they are a part of the package (that would be less). I just did it to give you a picture of how much they cost compared to each other. Hope that wasn't too hard to get,
I suck at explaining. Any way, here's the list:

I want to go with the nxzt phantom big tower either in white or black but someone recommended me to get another one but i'm still questioning if that's really worth it. I really love the look of the nxzt phantom big tower, but if it really makes a difference if I got one of those other cases on the list, then i'll do that. But is there really that much of a difference? Or what would be best for this spesefic build?

Also when it comes to watercooling:
Is a watercooling system necessary or even good at all with this comp? If so which one of these two should I get?
Cooler Master Seidon 120M CPU cooler
Corsair H55 Hydro Series CPU cooler

Also sorry if this category wasn't the right one, there was no category for cases so I just wasn't sure.
