Bomberboysk list of parts is pretty good. I would buy everything he said except the following in my opinion:
Replace the Case, Antec Twelve Hundred for $180 with this:
Antec Nine Hundred Black Steel ATX Mid Tower Computer Case - $120

I would prefer a Gigabyte motherboard over Foxconn because their quality control is the best in the industry. Replace the Foxconn Bloodrage GTI X58 Motherboard for $234.99 with this:
GIGABYTE GA-EX58-UD4P Motherboard - $260

I would rather have two hard drives over one very large hard drive as you can copy whatever data you value very easily to your second hard drive. I have two hard drives in my system and I love it and will likely always be using two drives.
Replace the Western Digital Caviar Black 1 Terabyte Hard Drive for $105 with these:
Western Digital Caviar Black WD6401AALS 640 gigabyte Hard Drive - $75
http://www.newegg.com/Product/Product.aspx?Item=N82E16822136319
and
Western Digital Caviar SE16 WD3200AAKS 320 gigabyte Hard Drive - $55

Edit: There is my two cents worth and hope it is worth more than $0.02.
