CPU seems decent enough
1GB of RAM will limit you, I would make it atleast 2GB, preferably 3GB, or 4GB if you have installed a 64bit OS.
It also has an Nvidia Geforce 6150, really not meant for games, and while the game should startup, it really wouldnt be playable on even low settings. You could get a new graphics card if you want, assuming you have a decent enough power supply in there.
Ah, it says its a micro tower as well....that will really limit your choices on video cards too.
