    I paid extra bucks for the case. I found out it needs assembly. There is no instruction and the provided screws are too short for their application half the time. Since I am not gonna move it around I somehow made the case to cover the unit. So it will be OK. I was relieved the light blinked when plugged in. It means working? I hope.
