It's quite decent, but the price is a little ridiculous. Also, it's good to note that compared to other games, Minecraft uses quite a high amount of resources, much more than Skyrim. A fast CPU (the linked PC definitely could handle it), graphics card (mmmhhhh...) and a reasonable amount of RAM (16GB is more than enough) would be needed to run Minecraft at max.
I'm not quite sure about the minimums of 60fps at maximum settings, but I'm guessing it would require at least an nVidia Geforce GTS 450 (use
