[Finally a TT Product Owner, but i need some help]

The product in question is the Core P5 because well..... CES 2016, but to the help,

 

I saw in some pictures i see that the PSU has a cable cover and in others there is not, so heres where my pondering has landed me, does it come with the box or do i have to buy it from somewhere else? and if so could someone hit me up with a link because i think it finishes off the case perfectly
