The design is awesome so I'd definitely not change it!
I would have liked to have WoL working, that is an important feature for those who don't plan on having it on 24/7. (I know, a NAS is intended to be on 24/7, but to have something more environmental friendly, the ability to turn it off and on without physically touching the device is a must)
Other than that, I'd also add the option to disable or at least deem the front leds (can't place it in a visible place it near the TV).
and ECC ram would also be very welcome.
