O_Shovah, good idea to summarize the list of tasks remaining. I would add to it:
1) Decide if we should switch from the LMZ12010 to the smaller and cheaper LMZ12002 (or 3) for the 2.5V rail.
2) Did Olaf change the feedback resistors to the suggested ones in the power supply datasheet?
3) Decide on cooling method. These could mean leaving mounting holes (or clearance for the Radian EZ-Clip) and fan headers.
