All the 1TB drives available on Newegg are OEM drives which do not come with cables of any type.
If this is for the build up you're doing, the SATA cables are included with the motherboard and the power supply has the needed SATA power connectors. You could always purchase the adapters separately if you really need them.
When ordering direct you get it all for the "higher" full retail price over finding any rebate offers at newegg, TigerDirect, or another vendor. Newegg usually sees the lower price while not being the only place to look. How about a 1.5tb Seagate model seen retail apparently at http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4138742&CatId=139
