The best is A-Power Pick out your components and they put it together for you. I have never had 1 person get screwed when I recomment then to A-Power. Cant say that about NCIX or Atic.
A-Power actually cares about people and will try to build you a decent system that suits your needs. I send all of my customers to A-Power.

BTW I work at Shaw cable and have seen my share of useless,slow,NEW computers.(several thousand)


A-Power first, then Anitec, then NCIX, and of course Dell if you dont know squat...they are the laymans decent option.

Future shop and Best Buy will sell you whatever you're willing to buy, so beware. Tigerdirect...good deals...plus shipping.
