Is the front panel USB 3.0 or USB 2.0 must to have in a computer cabinet? I thought USB 2.0 & 3.0 sockets come on the back side of the cabinet where the mother board is attached, are they enough? or do we need them on the front side too? The above question i have asked in relation to a statement made below for a computer cabinet at one of the internet sites - this is the statement - "No USB 3.0 port in front panel header"
