I had one of the very early soekris boxes and found it to be a gem. If a 5x86 133MHz processor meets your needs, you'll like it a lot. I haven't tried the net4801 board, but I've worked with other Geode designs and if you need more cpu, that'll probably do. Good luck. -- "Where am I, and what am I doing in this handbasket?"
