This is a Biostar barebones system that includes a Sempron 3300+ CPU and on-board nVidia 6100 graphics (very decent by on--baord standards). Take into account that it comes in a very neat, attractive little case with a Motherboard ans PSU already inside and you're on your way to making a very nice little office/work/media centre PC. It's solid value rather than a spectacular system.
