Consumers will still be able to customize their computers to include a CD-ROM drive, but they won't get a discount, so requests for the older drives should be minimal, said a spokeswoman. The shift from CD-ROM drives and CRTs has been taking place slowly but surely across the industry. Most computer companies have largely phased out CD-ROMs in favor of CD-RWs, offering CD-ROMs only in the cheapest models. |

You get the features you want and when I built a PC, it came out a little over half the price of a new one.
Also, when you buy a motherboard, it is far more customisable and expandable than the an OEM board, e.g. in Dell, Compaq, etc. Unfortunately, there are many people who don't know much or anything about hardware or building PCs and this what the big companies take advantage of. I've seen many new PCs that people have bought recently where the shop has put a password on the BIOS.
