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....
