I should also point out that getting three 250's is handicapped. The cards are some of Nvidia's lower models and you would benefit more by buying a better single or double GPU PCB.
Also, don't get 3 high capacity drives. 1 and a SSD would probably leave you better off.
I'm not very experienced with PSU's, but Amacrox isn't a brand that I've heard of. I would go with a major brand such as Corsair, Antec, or Silverstone.
