Typically with a boxed processor you receive a heatsink/fan and the thermal grease. It looks like you have a nice build spec'd out there. The only thing I might caution you on is the SSD drive. They are very fast and if that is what you are looking for then go with it... however you mentioned 3D rendering so I am thinking you may need more space. The speed will help with the rendering however storage size will matter quite quickly as you progress. You could start with this build and later add another larger drive such an HITACHI Deskstar 1TB for storage.
