& If you are wondering why I don't list your favorite vendor or manufacturer, it's probably not because I'm being selective. Please send me e-mail if you want to see another site. My only criterion is that the listing must be of someone who deals with motherboards on a daily basis. Absolutely NO one-time offers or "slightly-used" motherboards. Also, since this site is geared toward people who want a name brand (or at least know what to look for), I'd like to only post vendors that list the brand and/or manufacturer AND they list more than one motherboard. Many vendors carry only one motherboard and just swap out the CPU for the speed you want it. This is why I like to list vendors with "no CPU" prices.
