I'd just go for a nice simple case that you won't regret buying. Obviously you
can go for a nice case with translucent sides, but you don't need to have a tacky colour on the front; hence the reason I'd just go for a nice black and silver case or something.
As for the liquid cooling, it is obviously a great idea to invest in something that's quiet, but is it really worth spending all of that extra money that you can just get a few 120mm fans for instead, that do the same job but are just a little louder. Think about it, save money on buying a nicer case for cheaper (try overclockers/misco), leaving more disposable cash for better, more important hardware - like cpu or ram.
Edit:
The Soprano case that you posted is really nice, I was going to get one like it myself, but have a think about your budget and what you should really spend the most cash on (like I said above).
Cases from overclockers - there are some pretty nice cases on there for ~£80, like the
Antec Sonata III Piano Black Quiet Case - EarthWatts 500W PSU, that's pretty hot.
Look at the Antec cases, they're nice.
Also, the Soprano case that you've got there, this one's nicer:
clicky.
much love, lol
