I just started the first board (motherboard), and I know it’s too late now, but the spacing for the holes for resistors (at least on the motherboard) is waaaay too tight. I had to bend the leads right at the edges of the body of the resistor to get it to fit. The holes are about 7.2mm (9/32 inch) apart. A more typical distance is 12mm (about 1/2″). I suspect this is a problem throughout all the boards which will make them not fun to solder.
