The NZXT H510i ships in a fully colored cardboard box with an image of the chassis on front and a closeup of the I/O on the rear. You will find specifications and further details on the sides of the package.
A plastic bag has been put over the case to protect it from scratches and fingerprints during packing, and two sturdy Styrofoam spacers keep it save during transportation.
NZXT includes a full set of black screws alongside an ample number of zip ties. You will additionally find a splitter cable for the combo audio port and an adapter to separate the solid case connectors in case your motherboard needs it. Last but not least, there is a detailed manual, which will help with assembly.
