If you are looking for a new case to house your components, I would strongly suggest taking a look at the Antec P183 computer case. I was able to achieve some good-looking temperatures and the overall build quality of the case is excellent. You will be able to hide just about all of your PSUs cables that maybe messing up the look of the inside of your current enclosure solution. Antec has packed many awesome features inside of a nice looking chassis without going overboard and making it too cluttered.
