Thats a full tower, so anything is ideal. Its not about the case, its about $$. Never let a case limit you. I would check out Dangerden's WCS. Since Thermaltakes arent very good. But if you want something simple, whithout demanding results. Thermaltakes big water works just fine.
I suggest PM Nubius, he has a Thermaltake WCS for sale.
PP - I have had a danger den setup for a couple weeks now:
Yeah yeah the waters pink...it'll be red when I go to AMD64 because I didn't put enough dye in this last time around in fear of killing performance.
I still have that bigwater, but I'll probably use it to cool a pelt and see how far I can push this XP-M once I go AMD64, but I'll only need it for that little bit then can probaly get rid of it after that.....I probably won't be able to do that little experiment until a month from now though.
