u can choose the parts and they'll put it together, though if you do enough reading and research, you could order the parts and build it yourself
it lists your fsb at 133 (should be 166).
Also, it lists your motherboard as an "ASUSTeK Computer INC. Mobo Model A7N8X.
If you are throwing via drivers on an nforce board, you are asking for trouble
if you don't know the difference bwetween xp home and pro, then chances are you won't need pro.
And the 256 card is worth getting as long as you have oodles of cash and do not cut corners on other componants. Otherwise get the 128 and a better cpu for example
truepower: "Dedicated output circuitry for each voltage output, overcomes the limitations of combined output of traditional design. Get all the power you need when you need it most."
smartpower is just a regular psu.
