Nvidia NFORCE 680I - Manual (Page 9)

Intentions of the Kit
This kit provides you with the motherboard and all connecting cables necessary to install
the motherboard into a PC chassis. If you are
building a PC, you will use most of the
cables provided in the kit. If however, you are replacing a motherboard, you will not need
many of the cables.
When replacing a motherboard in a PC chassis, you will need to reinstall an operating
system even though the current drives have an operating system.
