Reply to Going to switch over to a DJM 800 + X1 setup for house parties, Do i need Audio 6or8?

Okay so im believeing im going to sell my mixtrack pro & f1 to cover the cost of a traktor soundcard and a case for the DJM & X1. I have numerous questions on this setup however.

1:
Do i need a Audio 6 or 8 for this? does it have to be Traktor or Komplete?

2:
Is there a case that fits a DJM 800 and X1? As well as a soundcard and laptop maybe?

3:
With this setup, would i be able to use the DJM normally? (e.g. inbuilt effects and colour effects) also would my speakers be connected to the DJM, or the soundcard?
