^ that one's alright for normal usage. The graphics card is kinda weak though. So if you don't play games it's a good buy. Or you can just upgrade it. I've never bought a refurbished computer before though.

I personally prefer building my own computer because i get the flexibility to get more performance out of my computer by overclocking; had my Q6600 running at 3.6GHz. And if something craps out, i have the ability to replace it w/ ease. And I tend to play some computer games too, so I try to squeeze the max performance outta my components. I guess i like to customize everything, from my computer to my car... haha

The computer u posted is good enough for most tasks minus graphics intensive gaming.
