The 'hard' drive is on a IDE to Compact flash interface. These things
are almost all wiring. I do not believe they are an IDE to USB
converter. Afterall, the Compact flash is a drive, so it is a matter of
wiring and power. (there is only a couple of capcitors on the PCB and a
place to plug in a drive power connector.
So the bottle neck is the Geode GX500 (articles equate it to a 366Mhz
Intel processer). But if I can find another nice micro system like the
decTOP with a little more speed, at that price point, I would grab it....
