I too got feed up with Dell, Compaq, IBM, you name it.  I found a supper gaming machine that didn't cost me an arm and a leg, I got it online from Volecity Micro.  They built the machine I wanted.  They built it , they tested it for ten days before shipping to me.   they provided a complete set doucmentation that you can really use.  Plus they proivded a complete system backup, so no matter what I did, I could always recover.
