Shipping a desktop PC is not an easy task, and you have to make sure that the system arrives at its destination intact. The Chimera 4SE was boxed up in the original NZXT Phantom box that the case arrived in, with the internals being secured with a vacuum foam block.
The system arrived with no damage, save for a video card that wasn't working. The damage to the card was not from shipping as far as I could tell, and likely was sent from EVGA defective.
Included with the system is an iBUYPOWER keyboard and mouse, both of which are pretty terrible. The mouse does come with adjustable DPI, but won't cut it for the serious gamer. The keyboard has mushy keys and shouldn't even be bothered to be plugged in.
The extra cables from the modular PSU are included with the system, along with the other various "spare" parts that one collects when building custom systems.
