NZXT ships the Source chassis in a plain cardboard box, just as they did with the H2. Seems like NZXT is steering clear of full color boxes for their budget and mainstream offerings. While this is by no means a bad thing, In the end the contents really count. NZXT actually manages to convey the advantages of the chassis in fairly high detail considering black is the only color at their disposal.
Two basic Styrofoam spacers hold everything in place - perfectly sufficient for a chassis of this weight and size.
NZXT has included enough screws to comfortably fill the entire chassis with hardware. This is a step in the right direction as the Source 210 Elite did not ship with enough.
