Not as limited as you think....
You're looking at just the base unit.... Otherwise, look to MAXIMUM 2x 120GB HDD's (IF you used a standard IDE cable, and a power-splitter cord from the power cord to the drives.) I have mine as a simple server at home, and it does just fine.. I am still trying to find a alternative to the Cobalt OS I was able to obtain from SUN before they became Oracle.) I REALLY would love to be able to run a simple 5X USB IDE card, to the device, and be able to punch a few multi-SATA docks to the storage.. I would love to be able to feed it a variation of UBUNTU, called Ultimate Edition, and run it flat-out.. Since your remarks were back in 2008, about the time the unit was active, I'd say you missed the best parts later, before Cobalt folded, My only gripe, was the two weak cooling fans. I've seen people put the ever popular slot fans into the single PCI slot on the back, but i found a pair of super 2" fans that fit outside the two points, that move plenty of air!
