For the purposes of debate we will assume the object to be genuine. We will assume it to be a 6 to 8 month old prototype for a mobo destined for a 19" rack. We know that the Video card, processor card, RAM, Modem and Airport card are not present although easily recognisable connectors are available for all of them. This would explain why the G4 specs given are those of current CPU daughter cards. We know the mobo to be 28 volt and to use DDR. There is a "mystery" connector adjacent to the FW ports. The standoff passthroughs and clear space immediately in front of the processor slot suggest a very large daughter card. The indentations and arrangement of the mobo suggest 2 to 4 large fan/power assemblies. We will assume that we are looking at this board right way round and at it's rear panel. The depth of the USB, FW, Ethernet, etc. give us the rear panel placement. The standard depth from socket to frame tells us if the case indents for connections to any PCI cards. The connectors in the upper right appear to be drive cable connectors, but which kind? If those 2 are (say) HW RAID capable ATA 133 then what is the connector midway along the right side? Opticals? I want to go over this component by component to extrapolate the case design. we have until monday to figure it out.
