Is this a good computer build for the money?

your list looks pretty solid, go for the phennom x6, it is only 40$ more and much more powerful, you might wanna browse for a cheaper motherboard, maybe a sub-80$ (even at that, it would be really reliable) but other than that (unless you are a gamer, then you are forgetting GPU, --video card--) other than that the list looks pretty solid. hope it woks ou for you,
