Thanks for posting this story! I've had a pet project on hold for a little while that involves stuffing a similar Ion board into a 2nd rev. Sega Genesis (the sleek one with the oval trim on top) and was hoping it might run passive with just convection airflow, so I appreciate the reality check as my Genesis is nowhere near as tall as the N64 and barely fits the heatsink without the fan. Oh well, hopefully the Zacate (or similar) CPUs make their way to mITX as the TDP is a lot lower than atom+9400.
