This sounds like a good format, but I'm not sure I see the obvious
usage. It does not have number crunching capabilites, so the obvious
usage I see is as a file server, but it lacks somewhere to have the
file system. I guess you intend to go for the USB (2.0? a must) for
the disk connection then, or? How about an io port for IDE, so I could
add a few 100Gb and how about connectivity to other devices? You mention
neither bluetooth nor WLAN? Is the 60Mhz a temporary thing or...
otherwise with proper usage of the machine, 400 Mhz and a Gb or RAM
it will be quite a cool thing.
