Replaced my old and bad Dell Optiplex 330 MotherBoard with one from here and so far so good and working like it should!
I've purchased several refurbished motherboards from Discount Electronics for a Dell Dimension 4700, a Dell Optiplex 780 and, most recently for a Dell Optiplex 330. The customer service, tech support, shipping price and speed have always been exceptional. If you have a vintage computer that you like and want to keep it running, this is the place to go. Their boards are as good as new, if not better.
