I'm doing my first build...so I've got a number of questions. One is......has anyone heard parts vendors touting the idea of a 5.75" SATA Drive fitting into a 5.25" drive bay ? I hope your response is..."impossible". Because I agree with you. Plenty of the computer parts vendor sites are now selling SATA Optical Drives with the width of either 5.7" or 5.75" LG's home site is stating this. And TigerDirect is another. I know it's physically impossible....but these vendors are of the mind that it WILL work.
