At first I expected that the rack mount mounting holes would be on either side since many people want to mount them on the back of the rack. I also think the wall warts are a bad choice, they should have been internally powered. If you were going to use a wall wart, why not put a clip on the back to prevent the cord from falling and being pulled out? The USB3 cable looks nice and thick, but it's too short. Finally, the device has sharp corners that caught on my $60 shirt and ripped the threadsโฆ
