Hi
I think you're right about vibrations.. I was concerned about them but now that you make me think about it, resonance could worsen the things.
At this point then, if thinking about a tray design, the 2nd most important point is cooling... the Supermicro M34 has the sata ports lined at the bottom in line, so mounting a 12cm fan was easy.. the M35 has the sata slots parallel to each other, so space could be an issue..
if someone (whaler please?) has a M35 at hand... could you please use a ruler to measure the free space between the power and sata ports to check if a 12 cm fan would fit in there? (ie, not overlapping/covering the ports)
Many thanks!
