Fanless computer systems are tricky to keep cool. I have a little computer around here somewhere (can't find it at the moment though) which has a rubbery (silcone?) block that fits between the processor chip and the case - presumably thermally conductive and electrically insulating.
Anything that can provide a good thermal path from the hot items inside the case to the case inner surface would reduce the peak temperatures quite a bit. The case, being larger than the chip, spreads out the heat transfer and would not get as hot as the chip. Some of the newer PC cases and motherboards include 'heat pipe' technology to carry the heat from hot spots to finned heat sinks which can get rid of the heat. Perhaps one of these gadgets could be found or made to fit the Soekris cases. Old laptops are sometimes cooled during charging by standing them on end so the air circulates better around the hot bottom. Attention to how the Soekris case is mounted could help in this way (with internal heat path augmentation). Hope this helps. Let me know as I have a 5501 (somewhere around here).
