I have recently ordered (2 days ago) a barebones kit from tigerdirect, I have 2 questions about it, I assumed they dont come pre-assembled, but do they include the things like sata cables and other connectors that might be needed? And when they ship the items do they ship them individually??
No, SATA data cables are not usually included. SATA power cables will be included.
It is best to wait until you receive the package and start assembling the computer. Then go out and buy just the additional cables that you need.
Yes, parts may be shipped from multiple warehouses, and sometimes drop-shipped from the factory warehouse. Generally, everything will arrive within a couple of days of each other. Only exception is if any parts are back ordered.
