My laptop recently overheated and the motherboard "crapped" out. I've decided to build a desktop using the system builder marathon's hardware listing: http://www.tomshardware.com/reviews/radeon-hd-6950-unlock-build-a-pc-overclock,2893.html

I'm a bit new to building PCs, but I think this will be a fun experience. I almost just simply bought another laptop, but a friend of mine handed me a case to get started with so I guess here I am. He gave me a "Kandalf LCS" case... With the configuration in the March 2011 $1000 build list and this LCS cooling case, how much power would my PSU need to supply? Also, is it a good idea for a person new to building computers to start with LCS?
