According to the Tweaktown unboxing
and review, there is one mini DP to DVI in the box. Though I thought that I read somewhere that there would be two. Anyway worst case you will only get one and if you need more they are inexpensive at monoprice
. Enough so that you can have a couple spares around.
Just a heads up, if you decide on some DVI cables, get the 28AWG ones as the 24AWG are too heavy duty and do not have much flex in them and can stress the monitor ports on some monitors depending on the clearance.
