imo, the best case for cooling and quietest would be a steel case, very sturdy, and several large 140mm low rpm fans to blow pleanty of air in through the front, than one or two fans to help exhaust that air out the back.. people have their own opinions on what a good looking case looks like.. my opinion? i think a solid black, meshed front, no door computer case made of anodised aluminum or steel would be the most attractive. it could look heavyduty and live up to its looks. much like my lian li PC-A71f.. i would prefer it doesent have lian li at the bottom of the door. but i cant complain its by far the best case i have ever used.. wish some of the parts of the case were steel though, like the hardrive rack.. although its the most sturdy one i have ever used. i think the hardrives are the one thing that case manufacturers need to pay the most attention to.
