[quote name='AtlusParker']As an aside, OEM products do not come with a manufacturer's warranty. Correct?[/quote]
OEM products normally carry no warranty, since the OEM will integrate it into something they're selling and offer the warranty on the completed product. OEM in this case being HP, Dell, etc., for computer equipment. If they do have a warranty, it's almost never the same as the normal retail warranty.
One odd exception to this that I know of are Western Digital Cavair SE hard drives. In a retail pack, they're 1 year warrantied. OEM/bare drive, 3 year. Go check on the WD website and you'll eventually find it.
OEM software, such as an OEM copy of Windows, can't be sold without a piece of hardware, which is why when you see a really cheap copy of Windows XP, you get a piece-of-crap mouse to go along with it, or something like it.
