I'm planning to order a x6800 within the next couple of days and am going to get one of those Asus nfroce 4 motherboards which support SLI, the SE edition. i forget the name 
I'm not planning to overclock, so would the stock be sufficient as well as quiet? If not, what would be a good CPU cooler? Someone recommended the Scythe ninja so I was going to get that, but just thought i'd check here if anyone has any other recommendations, and if I even need it. Don't have a budget really, but don't want to go to watercooling.
I'm still deciding on a case, so not sure about that. Would something that big fit in most cases though?
Also, is installation easy? do I need to buy something to be able to install it? first time build.

I'm going to to tottenham court road again today and look at more cases though, so let's see how that goes.
