I wouldn't buy it...but, I'd say $250 to $300 would be more than fair...

i didn't notice some stuff a minute ago.

Very low end parts. I would pay no more than $350 for it.

kinda old parts but a new graphics card. I would pay 500 for it since it came with vista right? $100-200 dollars and Nvidia9500 about $100.

Power supply is low though and not sure what brand it is.

Maybe $300-$350... older parts plus a GPU that isn't very powerful

200$ at the most
