I absolutely recommend this case:
Antec P182
You might think it's a bit much for a case, but it is very well designed for keeping your parts cool, the airflow going, and best of all, silent as a mouse. If you buy this case, you pretty much don't have to buy another case ever again. This is one that I would be comfortable with reusing time and time again. It's within your $1500 budget too.

The Antec solo is a good choice too. Same company, same fundamental design. I just get giddy when I see the P182. Your choice.
Other than that, even though the guide AND the writer of the guide (I wrote in and asked him about it) say that a 380W power supply is okay, I still am a little weary about it. I had never heard of that before I read that article, so my previous education/instinct says to look at least 600W power supplies. If you do get it though, I am very interested on how it works for you. And if it doesn't, just buy a new PSU. It would still be in your budget lol.
