buttom view - you can open the Fonera, by removing two of the

inside view - with a few extra blue heatsinks.
The fonera 2100 originally got quite hot, even
though it had a good size silver-color heatsink attached. It was still
advisable mount it in the upright position and not flat on the back, when
running it for days at a time. Mounted on a "wall" would facilitate
a be better airflow.

I wanted the box to be cool and quiet at all
times, so I added a larger heatsink
I think it is a chopped-up pentium 4 heatsink. Also added the RAM
Fonera with additional heatsinks
