antec p180 is the best choice. its quiet and has good cooling. its not bad looking either, only problem is i hear its kind of tough to build. I just got one myself and Im waiting on a couple more parts so I will find out soon myself
The P180 is good if you want a silent PC build. Otherwise, I prefer the Antec Sonata II. It's a very glossy black and I've already ordered one from eBay. Should be arriving in a week or so.
