The only recommendation that I've heard is to have Mercury closest to the power supply.  This is because the fan is on that side of Pandora and will blow air on to the ADC, which can get rather warm.

I have traditionally put Excalibur between Mercury and Penny, just from the aspect of having the clock lines between those boards be shorter (whether this matters or not hasn't scientifically been proven).  Like you, I run Metis in the last board slot.
