To my great suprise, my A1222 Plus motherboard arrived today. When I last checked the tracking still said it was in New York. A long way from California. Anyway, I spent the day assembling it with the components I had already purchased a while ago. Unfortunately, I didn't have a SATA cable, so I couldn't get the OS installed and see it running yet.
However, I did create a blog with a lot of pictures and a few words on the components I am using. If anyone is interested, you can find it here:
