I've been looking for any reports that anyone has seen a single processor G5 yet (either 1.6 or 1.8GHz). The closest thing I've come to knowing how they compare with the insides of the dual is on page 70 of the preliminary G5 developer's pdf. It shows that the processor is located at the top of the RAM/Processor compartment, and that there are two RAM slots at both the top and bottom of the compartment. I gues the RAM slots are like that to make it harder for people to put the pairs of DIMMs in wrongly. Does anyone know it there are still two fans in front of the processor (and behind, at the back of the unit too)? If the rumors (on page 2 at the moment) are true about the single processor models coming out first, isn't it odd that all the units seen so far are duals?
